Weight gain in a 6 month old girl Factors contributing to the growth of children. Anthropometric parameters at birth - what is the norm in newborns
At the pediatrician's appointment, each baby up to a year is weighed monthly and measured for growth. Why is it so important for doctors to know how a child is growing and how much he is gaining weight? What do these parameters say, and what are the anthropometric norms for children of different ages?
Where did the weight and height indicators for children come from and why are they needed?
Anthropometric data of a child are one of the main indicators of the physical development and health of children. Significant deviations from the normal values of height and weight in a child almost always indicate the development or presence of certain diseases. So, if a child under one year old with adequate nutrition does not gain weight well, then this may be one of the symptoms of rickets, anemia, immunodeficiency states, diseases of the endocrine or central nervous systems.
A significant growth retardation may indicate a lack of somatotropin growth hormone in the body, and a clear excess weight with normal growth and proper nutrition may indicate disorders in the adrenal glands, thyroid gland, and even the development of a brain tumor.
In order to detect and start treating such formidable diseases in time, doctors carefully monitor the anthropometric indicators of children from birth. Development standards are compiled by the World Health Organization on the basis of many years of research. In addition to the average standard indicator for each age, the limits of the norms were also calculated. Weight and height above this limit is considered high, and below - low. It is for such children that doctors begin to observe especially closely.
WHO table of height and weight for girls under 1 year old
According to the norms, a healthy full-term girl is born with a height of 49.2 cm and weighs 3.200 g. This is the average. The lower limit of the norm for a newborn is a height of 47.3 cm and a weight of 2.800 g, and the upper one is located at values of 51 cm and 3.700 g, respectively. Values outside the lower and upper limits of the norm are marked as very low or too high. Doctors will observe such a newborn and, possibly, additionally examine it.
During the first month, the newborn should grow by 4.5 cm and gain a kilogram. The lower limits of the norm for a monthly girl will be 51.7 (height in cm) //3.600 (weight in grams), and the upper limits - 55.6 //4.800.
Normal indicators for a two-month-old baby: 57.1 cm and 5.100 gr. The lower limit of the norm is 55//4.500, and the upper limit is 59.1//5.800.
By three months, girls grow to 59.8 cm and weigh 5.900 grams. Low for a three-month-old baby is considered to be less than 57.7//5.200, and high is more than 61.9//6.600.

By five months, girls should grow to 64 cm and weigh 6.900 grams. Low rates - parameters less than 61.8//6.100. Indicators 66.3 // 7.800 are the upper limits of the norm for a five-month-old girl.
The age of 6 months is considered an important milestone in a child's development. A six-month-old girl should grow to 65.7 cm and weigh 7.300 g. The lower limit is 63.5//6.500, and the upper limit is 68//8.300.
A seven-month-old baby grows to 67.3 cm and weighs 7.600 grams. Scores below 65// 6.800 are considered low, while scores above 69.6 //8.600 are considered high.

A ten-month-old baby, according to the norms, should be 71.5 cm tall and weigh 8.500 grams. The lower limits of the norm for ten months are 69//7.500, and the upper frames: 74//9.600.
By eleven months, a normal girl grows to 72.8 cm and weighs 8.700 grams. Indicators less than 70.3//7.700 are considered low. High will be indicators exceeding 75.3//9.900.
By the year, according to the norms, girls should grow up to 74 cm and weigh 9,000 grams. The parameters 71.4 //7.900 are considered the lower limit of the norm, and 76.6 //10.100 are considered the upper limit.
WHO table height and weightfor boys up to 1 year
The norms for boys differ from those for girls, as boys are usually born slightly larger. So, a healthy full-term newborn boy is usually born with a weight of 3.300 grams and a height of 49.9 cm. These figures are considered normal. The lower limit of the norm for a newborn is a height of 48 cm and a weight of 2.900 g, and the upper limit is at 51.75 cm and 3.900 g, respectively.

Table of height and weight for teenage girls
In adolescents, anthropometric data are monitored once a year. For an eleven-year-old girl, the averages are 144.5 (height in centimeters) / / 34.4 (weight in kilograms). Parameters less than 136.2//27.8 are considered the lower normative limits, and parameters more than 153.2//44.6 are considered the upper ones.
Average height and weight for a twelve year old: 150//40.7. Lower limit of the norm: 142.2//31.8, upper: 162.2//51.8.
A thirteen-year-old girl normally has the following indicators: 155.8//44.3. Lower data bar: 148.3//38.7, upper: 163.7//59.

Table of height and weight for teenage boys
Boys between the ages of 10 and 14 years are slightly behind girls in growth, this is normal, since hormonal changes in boys begin a little later than in girls. But after fourteen years, guys begin to grow more intensively than girls, and by the age of 15 they overtake them in terms of growth.
In adolescence, anthropometric indicators significantly depend on genetic predisposition, therefore, when monitoring the physical development of adolescents, it is recommended to focus not so much on the average, but on the limits of the norm indicated for each age and on the child's heredity. So, if the father of a young man has a height of 190 cm, then the height of 182 cm of the teenager himself at the age of 15 can be considered the norm in this case.
For an 11-year-old boy, the average figures are: 143.5 (height in centimeters) / / 35.5 (weight in kilograms). Parameters less than 134.5//28 are the lower limits of the norm, and parameters greater than 153//44.9 are the upper limits.

At seventeen, the average height and weight are 176.6 / / 66.9. From the border: 166.7//54.6, to: 186//80.1.
Video "The height and weight of the child, Dr. Komarovsky"
Every mother knows that An indicator of the health and normal development of an infant is weight gain. Doctors at the hospital say you need to monitor this parameter constantly.
Check weight and height on the day of discharge from the hospital.
As soon as the baby is born, their height and weight are measured. They check the weight on the day of discharge from the hospital. This is necessary to see if the child is developing normally, if there are any deviations from the norms generally accepted by the Ministry of Health. Such deviations may include lactose deficiency in infants, symptoms which you can find out by clicking on the link.
It's believed that the weight of each newborn is considered normal if it is in the range from 2.7 to 3.7 kg . And in most cases, babies are born that way. Therefore, it is important for new parents to know how weight gain occurs in infants by months. The weight gain table will help you keep track of this parameter.
The initial value of the weight of the newborn is affected by the diet of the expectant mother.
1. Health child;
2. Heredity ;
3. Floor;
4. The diet of the expectant mother , as well as her mental and physiological state ;
5. Mother has bad habits .
Babies and artificials - what's the difference
Weight Gain in Breastfeeding Babies and Artificial Babies not the same. Weight gain in an infant occurs naturally and evenly, it is hardly possible to overfeed him, he will only eat as much as he needs.
Weight gain in an infant occurs naturally and evenly. Artists, as a rule, suffer from overweight, which is gained due to overfeeding.
Find out if your child's weight is within limits can use various formulas and tables.
Komarovsky formula for calculating body weight
The pediatrician Komarovsky proposed a formula by which it is possible to calculate the weight of a newborn under the age of one year.
Doctor Komarovsky. Optimal / estimated weight (M) calculated as follows :
M= m + 800 x n
m- newborn baby weight
n– age (in months).
Example:
If at birth the weight of the child was 3200 grams, then at the age of 6 months he should weigh:
3200+800 x 6 = 8000
WHO weight gain chart
There are other ways to find out if a child's weight and height are within standards.
In 2006, the World Health Organization proposed weight gain chart for babies by months. It shows the relationship of the child's age (from birth to a year) with his height, weight, and other basic parameters.
WHO weight gain chart. It is important for young parents to know how weight gain in infants goes by months. The table shows us the following pattern - if the difference in height in babies of both sexes is approximately 1-2 cm (boys are taller), then the difference in weight increases with age.
In the first month of life at first it is about 0.3-0.5 kg, starting from the age of three months, the difference reaches 0.6-0.7 kg. Leadership of course for the boys.
Features of weight gain in boys
From the same table of weight gain in infants by months, you can see how the boy's height changes. If a the difference in height in the first three months of life is 3 cm , then further this parameter grows not so fast, and in subsequent months increases only by 1, less often 2 cm.
The same can be said about weight. In the first month of life, the boy adds 1.2 kg.
The difference in weight between an 11-month-old and a one-year-old boy is only 0.2 kg. Then this figure goes down, the difference in weight between an 11-month-old and a one-year-old boy is only 0.2 kg.
Features of weight gain in girls
The same table shows the standards for how, ideally, weight gain in infants should go on for months in girls. The height of a newborn differs from the height of a girl who is already a month old by almost 4.5 cm, while the weight at the same age differs by 1 kg.
As the girl grows gains 1-2 cm in height, weight gain decreases every month. The weight of a one-year-old girl differs from the weight of an 11-month-old girl, as well as for boys, 0.2 kg.
Girls are smaller - according to the table, they should weigh 9 kg. At the age of one year, the weight of a boy should reach about 10 kg. Girls are petite - according to the table, they should weigh 9 kg.
Now the mother herself can observe and control how the weight gain in babies goes by months, the table clearly shows this.
Norms of weight gain
In the first six months of his life, the baby should Gain 600 grams of weight every month In the second half of this the value decreases and is already 300-500g.
If the weight of the baby differs from the tabular data by 12-14%, this is considered normal, there is no cause for concern. A big difference is a reason to see a doctor.
If the difference from the tabular data is more than 10%, you should already contact a specialist. With growth, the situation is more complicated. If the difference from the tabular data is more than 10%, you should already contact a specialist.
Underweight: causes, symptoms and consequences
Of course, the table reflects how the weight gain in infants goes by months. But if the weight of the baby is different from what is indicated in it, you do not need to immediately panic. Small deviations from the tabular norms are permissible.
Low weight may be due to the following facts:
Constitutional features of parents.
In a family of thin parents, a fat child cannot be born, and vice versa.
Difference from tabular data is acceptable for individual regions.
Affects the weight of the baby and the type of feeding.
To determine the baby's lack of weight, only weighing will not be enough. It is necessary to measure height, conduct a survey of parents, examine the child and take all the necessary tests from him.
A newborn may not gain weight well due to frequent illnesses. A newborn may not gain weight well for a variety of reasons. Here the main causes of malnutrition (lack of weight) :
Availability diseases;
Improper nutrition;
Neurology;
Dysbacteriosis or poor digestibility of milk;
Fast fatiguability child;
Improper organization of the feeding procedure.
The consequence of all these reasons is the fact that the child does not eat enough, and therefore does not gain weight.
Hypotrophy can lead to a number of other diseases:
low immunity
the child often gets sick SARS
;
Anemia
;
Rickets
;
Endocrine dysfunctions
(manifested in adolescence, delayed sexual development);
Changing the color of nails, hair, etc.

The average weight is normally 3.2 kg. At the same time, the lower limit of weight for girls is 2.8 kg, and the upper limit within the normal range is considered to be 3.7 kg.
For the average value of the weight norm is 3.3 kg. Weight in the range of 2.9–3.9 kg is considered normal.
If the weight deviation from the indicated limit values reaches 400-500 g, the pediatrician may suspect the presence of developmental disorders and prescribe additional examinations.
The growth standards for newborn girls, according to WHO, are 47.3-51 cm, and the average value is 49.1 cm. For boys, the height is considered normal from 48 to 51.8 cm. The average growth rate for boys is 49.9 cm.
It is important to bear in mind that all the above norms are averaged. It is impossible to obtain an adequate assessment of the physical development of a child simply by comparing height and weight with WHO indicators. Since each child has individual developmental characteristics, some deviation in the weight or height of a newborn from WHO standards is far from always a sign of any violations.
According to Russian pediatricians, the growth rate for full-term is considered to be between 46 and 56 cm, and normal weight is from 2.6 to 4 kg. As you can see, these figures are somewhat different from the WHO data. Therefore, an experienced pediatrician should analyze the growth and weight indicators of the baby: only he will be able to take into account all possible factors in the development of the child, adequately assess his condition and draw correct conclusions about the absence or presence of any violations.
Norms of increase in height and weight of newborns
The baby is considered in the first four weeks of life. How does his weight and height change during this period?
In the first 3-5 days after birth, the baby loses about 6-8% of body weight. This is a natural process that is caused by physiological factors: the release of meconium, the drying of the umbilical cord residue and some loss of fluid. In addition, in the very first days of life, the baby receives very little milk from the mother.
Already on days 4-6, the body weight of the newborn begins to increase, and by the 7-10th day the child's weight is restored. Weight loss of more than 5–10%, as well as slow recovery of body weight, may indicate any congenital disorders or be a sign of a developing infection. By the end of the first month of life, weight gain normally ranges from 400 to 800 g.
As for the growth rate, after the first month of life, the baby should grow by at least 3-3.5 cm. But often the growth of a newborn in the first month is even more intense - the child can grow by 5-6 cm.
While all children grow at their own pace, there are growth rates for each age group. Parents should know them, firstly, in order to timely identify and correct a health problem, if any, and secondly, in order to buy clothes for the child in the right size.
Instruction
To determine the growth rate, pediatricians use centile tables. Any parent can interpret their data if they understand the principle on which they are built. For example, for the growth rate in the centile interval of 3% is 45.8 cm. This means that only 3% of the female sex does not reach this height at birth. Centile intervals of 10, 25, 50, 75, and 97 percent are also used. If your child's height at a certain age falls within the 25-75 percent centile interval, then you have nothing to worry about, since the baby's body length is normal. If the indicators are in the range of 3-25% or 75-97%, you should consult your doctor. Perhaps everyone in your family is tall, then it will be completely normal for a child to be ahead of their peers. However, deviations in growth rates may be associated with impaired functioning of the pituitary gland, which can be determined in a timely manner and, if necessary, corrected only by a specialist.
Your pediatrician may use child development corridors to assess your child's growth. In total, 8 corridors are distinguished, and the interval from 3 to 5 is considered the norm. The values of these indicators fall within the previously described framework of 25-75 percent centile intervals. If you have a girl with a height of 51 cm, which corresponds to the 4th corridor of development and indicators of a centile interval of 50%, this does not mean that she should continue to fall into this norm. Growth, like other indicators, depends on many factors: genetic predisposition, the amount of substances entering the body necessary for its development, and health in general. If in some period the deviations amounted to 1 corridor or centile interval, do not worry. But you should monitor sudden changes in the growth rate and report this to the doctor.
Approximately by the end of pregnancy, most mothers begin to think about how much her future newborn weighs, because his weight is an indicator of the state of health, as well as full-fledged intrauterine development. Immediately after birth, each baby is examined by a neonatologist, carefully measuring his height, weight, chest and head volume. All these indicators eloquently tell the doctor about the state of health of the newborn and the possible presence of any pathologies. Having been born into the world, the baby for the first six months will eat only breast milk or, in its absence, an adapted milk mixture. In order to understand whether the baby has enough nutrition, how it is absorbed, how the baby develops, pediatricians measure the weight of the newborn at least once a month.
Baby weight gain chart
There is a special table of weight gain for babies by months. Based on the data in this table, you can easily understand whether your child is gaining the necessary weight and height. To do this, simply add to the weight of the baby when discharged from the hospital the required number of grams corresponding to his age.
| Age (in months) | Weight gain (in grams) | Height gain (in centimeters) | ||
| per month | for the past period | per month | for the past period | |
| 1 | 600 | 600 | 3 | 3 |
| 2 | 800 | 1400 | 3 | 6 |
| 3 | 800 | 2200 | 2,5 | 8,5 |
| 4 | 750 | 2950 | 2,5 | 11 |
| 5 | 700 | 3650 | 2 | 13 |
| 6 | 650 | 4300 | 2 | 15 |
| 7 | 600 | 4900 | 2 | 17 |
| 8 | 550 | 5450 | 2 | 19 |
| 9 | 500 | 5950 | 1,5 | 20,5 |
| 10 | 450 | 6400 | 1,5 | 22 |
| 11 | 400 | 6800 | 1,5 | 23,5 |
| 12 | 350 | 7150 | 1,5 | 25 |
Why monitor weight gain in infants
Immediately after the birth of the baby, doctors measure his weight and write it down in the extract. Later, this figure will come in handy many times when calculating baby weight gain. In the first 3-4 days of life, a newborn loses approximately 10% of its birth weight. This happens due to the fact that during birth the baby experiences serious stress, which burns a significant amount of calories in his body, and, therefore, leads to the loss of part of the body fat. Also, babies drink colostrum for the first 3-4 days of life, which precedes the appearance of breast milk. This substance is very small, so kids cannot fully get enough of it. Usually, by the day of discharge from the hospital, that is, 4-5 days after birth, the baby's weight stabilizes. This figure is also carefully recorded in the extract. Later, the district pediatrician will "start" from this figure, making calculations of weight gain by the child.
After the young mother has milk, the baby begins to actively suck it and, accordingly, quickly gain weight. If he is gaining weight well, then the doctor will control his growth once a month. If the baby was born prematurely or with insufficient weight, its growth should be monitored every 2 weeks.
The World Health Organization (abbreviated WHO) has established certain norms for weight gain in infants. It is on WHO recommendations that the doctor relies when he draws conclusions about excessive or insufficient 
newborn weight gain. Why is it important to monitor baby's weight gain? Since the child cannot yet tell his parents about his appetite and well-being, the weight gain indicator can do this for him. When a child is breastfed, it is almost impossible to determine whether he sucks out enough milk and its saturation, because it largely depends on the diet of the nursing mother and the composition of her milk.
By weighing your baby after 2 weeks, you will be able to understand if he is getting enough nutrition, if he is full or if he needs additional formula. The same applies to children who are bottle-fed. The serving recommendations on formula packs are not always suitable for all babies. Excessive weight gain may indicate overfeeding, and too little weight may indicate insufficient calorie intake.
Norms of weight gain in infants
According to the WHO, a normal birth weight is between 2,700 and 3,700 kg. However, this figure may vary in one direction or another, depending on some factors:
- Heredity. The weight of the baby at birth largely depends on the genetic inheritance. For example, if one of the parents was overweight at birth, then the chances are quite high that his child will be born large. The same principle works with small stature or weight.
- The health status of the baby.
- Gender of the child. Most often, boys are born with a slightly larger weight and height than girls.
- Maternal diet during pregnancy. A direct relationship has been established between the consumption of high-calorie foods by the mother and overweight in the child. Therefore, it is important during pregnancy to limit the use of sweets and rich flour products.
- Bad habits of the mother. Newborn babies whose mothers smoked during pregnancy or drank alcohol are usually underweight, as well as some developmental delays.
- After the mother has lactation, the baby begins to actively suck breast milk. With good nutrition, the baby grows, as they say, by leaps and bounds. Several factors also influence weight gain after birth:
- The health status of the baby. It is no secret that when a person feels unwell, he eats badly or refuses to eat at all. Even in the old days it was believed that a good appetite is a sign of excellent health. The same thing happens with babies.
- Breastfeeding or adapted formula. Babies who use only breast milk generally gain weight more slowly than formula-fed babies.
- Feeding method. Babies fed on demand gain weight faster and more consistently than those fed on a schedule.
- The amount of food and its calorie content. When a nursing mother does not have enough breast milk, the baby will not gain weight well. The same thing happens when mother's milk is too watery and lacks calories.
- Appetite. Each person, including a newborn child, has his own special appetite. Someone from birth loves to eat tightly and satisfyingly, while someone prefers to eat often, but in small portions. In the latter case, weight gain is much slower.
- Child's age. In the first few months, the baby is actively growing and gaining weight. After 5-6 months, the child's growth and weight gain begin to gradually slow down.
It is important to remember that all people develop individually and have their own special body structure. The well-known pediatrician Yevgeny Komarovsky believes that the indicator of weight gain in infants is rather indicative. With minor deviations in any direction, you should not immediately panic and assume that the child has pathologies. Minor deviations from the norm set by WHO are the norm, and 
also do not require dietary adjustments and additional treatment.
However, if the newborn's weight gain does not occur or occurs too slowly, this is a serious cause for concern and an indicator that the baby is not getting enough milk. In this case, it is urgent to take measures to increase lactation or additionally supplement the baby with a mixture. Receiving insufficient nutrition, the body of your child will not be able to fully function, rapidly developing.
Excessive weight gain by an infant can signal overfeeding, which can lead to obesity in the future. It is very difficult for children who are overweight to lead an active lifestyle, which is necessary for proper development.
Height and weight are measured in a child almost immediately after birth, at the fifth minute from birth. These indicators are of paramount importance for assessing the condition of the baby throughout the first year of life. According to the cherished figures, doctors judge whether the baby is healthy and whether it develops normally.
Average weights for children aged 0 to 12 months
Normal weight indicators in infants up to a year have a significant relationship with many factors. For example, this is the chosen way of feeding and further feeding the baby, the lifestyle of the parents, and even the geographical location of the mother with the baby. But, despite all of the above, the medical community has developed a table with parameters as an example of the norm for most children under 12 months old.

The growth of an infant under the age of one year increases dynamically, with an eye to the constitutional features, genetics, nutrition and general health of the crumbs. A slight deviation from the average parameters is not a cause for concern. If growth rates are far outside the acceptable range, this is an alarming sign that requires a doctor's consultation.

On a note! The data given in the table are considered standard in assessing the physical development of infants. Nevertheless, it is worth remembering that babies are born with different weight categories and continue to add body weight unevenly. So, one crumb can “get heavier” by 0.5 kg in a month, and the other by a whole kilogram; but as a result, the increase in both babies can be considered normal, with an eye to their individual development.
How is the child's height and weight calculated?
The calculation formula is used if parents need to track the change in the baby's body weight, comparing each result with growing monthly norms. One of the estimated weight calculations used by pediatricians from the moment of birth until the first birthday is presented in a simple formula - M (kg) \u003d m + 800n, where M is the baby's body weight, m is the body weight at the time of birth and n is the current baby's age in months.
| Child's age | Monthly increase | Increase for the past period |
|---|---|---|
| 1 month | 600 g | ≈ 600 g |
| 2 months | 800 g | ≈ 1400 g |
| 3 months | 800 g | ≈ 2200 g |
| 4 months | 760 g | ≈ 2950 |
| 5 months | 700 g | ≈ 3650 g |
| 6 months | 650 g | ≈ 4300 g |
| Seven months | 600 g | ≈ 4900 g |
| 8 months | 570 g | ≈ 5500 g |
| 9 months | 550 g | ≈ 6050 g |
| 10 months | 500 g | ≈ 6550 g |
| 11 months | 450 g | ≈ 7000 g |
| 12 months | 400 g | ≈ 7400 g |
The rate of weight gain up to a year is usually recorded in the clinic with entries in the medical record, but they can also be controlled at home - using special scales. If in short periods the scales show a little less or more data in the table (with a difference of up to 150 g), then there is no need to worry, this is within the normal range.
Important!Sometimes the weight gain in a child differs significantly from the data given in the table. Parents should be alerted by large fluctuations in both directions. If the lag is more than 350 g or more, something is going wrong. Low body weight can seriously affect the development of the baby. If they go along with numerous complaints and disorders in the health of the crumbs, then the child must be examined by a pediatrician and a neurologist.
Table of increase in growth in infants from 1 month to a year
The growth from a child from birth can be influenced by a hereditary factor and, to a greater extent, by the constitutional features of the body of a little man. Growth spurts can be especially noticeable between 3 and 4 months and also between 6 and 8 months. At this time, in just one night, the baby can add a whole centimeter in length.
The calculation of the body length of the baby can be done using the approximate formula used by pediatricians: L (cm) = 100 - 8 (4 - n), where L is the normal body length, n is the current age of the crumbs.
| Child's age | Average growth rate per month | Height gain since birth |
|---|---|---|
| 1 month | 3 cm | ≈ 3 cm |
| 2 months | 3 cm | ≈ 6 cm |
| 3 months | 2.5 cm | ≈ 8.5 cm |
| 4 months | 2.5 cm | ≈ 11 cm |
| 5 months | 2 cm | ≈ 13 cm |
| 6 months | 2 cm | ≈ 15 cm |
| Seven months | 2 cm | ≈ 17 cm |
| 8 months | 2 cm | ≈ 19 cm |
| 9 months | 1.5 cm | ≈ 20.5 cm |
| 10 months | 1.5 cm | ≈ 22 cm |
| 11 months | 1.5 cm | ≈ 23.5 cm |
| 12 months | 1.5 cm | ≈ 25 cm |
Anthropometric parameters at birth - what is the norm in newborns?
According to the World Health Organization, the body weight of a full-term baby is considered normal if it is in the range of 2.5 - 4.5 kg. Moms and dads should be aware that WHO weight figures are generally indicative.
If the expectant mother has passed 9 months of pregnancy without serious complications, the weight of the child will most likely be 3-3.6 kg. If the baby was born earlier than expected (before the 37th week), then its weight will be an average of 2.5 kg. But you should not worry - a tiny newborn after a while will surely catch up with his peers. This is facilitated by compliance with the regime of sleep and rest, good nutrition and finding a little man in a favorable living environment.
The table below shows the height and weight of boys, as well as the height and weight of girls, as average parameters, indicating the order of maternal birth.
Immediately after birth, most infants lose up to 10% of their original body weight, as nature intended to rid the baby of excess fluid and accumulated meconium (feces). But after 7-12 days, weight loss is replenished:
- in the first weeks of life, the baby gains at least 125 g per week;
- from the second month of life, the set is 600-800 g for 30 days.
Noticing that the weight of the baby is noticeably lower than the prescribed norms, parents should figure it out - is there any reason for concern? Each baby develops at its own pace, so slight variations in height and weight are perfectly acceptable. If, up to the age of three months, the little one gains at least 0.5 kg per month, and from the third to six months, 0.3 kg each, and there are no complaints, then there is no reason for concern.
Important! Normally, during the first year of life, babies triple their initial weight (for example, from 3 kg to 10 kg). Often before 12 months, girls gain weight at a lower rate than boys. An acceptable difference in children of the same age can be up to 600-800 g.
How does a newborn gain weight (by week)
Active weight gain in infants occurs in the first eight weeks of life. This is a normal reaction of the child's body to a change in living conditions, and adaptation to a new diet and regimen.
| Age | What happens to baby's weight |
|---|---|
| First 3 days of life | Physiological weight loss (up to 7-10% of initial body weight) |
| First week of life | A newborn baby who is breastfed will gain about 100 g in weight in 1 week. |
| Second week of life | The peanut continues to grow and gradually gain weight. A healthy baby in 2 weeks will add up to 250 g to the initial weight. |
| third week of life | For 3 weeks after birth, the weight gain in the baby will average 150-200 g. |
| Fourth week of life | The first month is coming to an end. Over the past 4 weeks, the child has gained approximately 600-800 g. |
| Fifth week of life | The child is actively growing, eating with appetite and gaining strength for growth. The weight of the baby by the fifth week is in the range from 3.9 to 5.1 kg. |
| sixth week of life | During this week, the baby increases its body weight by 200-250 g. |
| seventh week of life | On the 7th week, the baby is gaining an average of 250-300 g. |
| eighth week of life | The rate of weight gain gradually decreases. By the end of the 8th week, the baby adds about 200 g to its weight. |
The digital value of indicators of growth and body weight in infants is very conditional and depends on many factors:
- the choice of feeding the baby (mother's milk or an adapted mixture);
- the amount of food eaten by the child per day;
- the presence of diseases that prevent the proper absorption of food;
- activity and the amount of time that the child spends in sleep and wakefulness;
- often - gender (often girls gain weight more slowly than boys).
Important! Pediatricians calculate the norms for height and weight for infants in conjunction with tables of the average statistical norm, but in some cases they use experimental calculations. Often a slight deviation of the indicators from the WHO tables is considered acceptable. Also, one should not forget about genetic heredity - if growth below average prevails in the family, one should not expect that the heir will add 5 cm per month.
Weight and height of the baby after birth - what to look for
In the maternity hospital, the weight and length of the body of a newborn baby are recorded and carefully monitored by doctors, especially in small and premature babies. They are weighed once a day at the same time, mainly in the morning.
- A daily weight gain is considered normal at the rate of 15 g per 1 kg of body weight. Growth is measured only once a week, and its increase will be assessed in 3-4 weeks. By this time, it should be at least 2.5-3 cm.
- Most infants gain weight rapidly after initial weight gain, especially during periods of "growth spurts". They occur around the middle of the second week of life, and then between 3 and 6 weeks.
- The average child adds an average of 20 grams per day. By the end of the first month of life, the scales in the clinic will show data of approximately 3.8-4 kg. The height and weight of boys is usually slightly higher than that of girls - the difference in weight can reach 0.4 kg and 1-1.5 cm.
The newborn weighs little - is there any reason to worry?
If a nursing baby was born prematurely or weighed very little at birth, then the norms in the increase in height and body weight for him will differ significantly from the norms for babies born on time.
The degree of prematurity of the baby (WHO information):
Birth weight largely determines a child's ability to adapt to life outside the mother's womb. If the baby was born 2.5 kg, this process will take place without deviations from the desired course. If the baby "did not reach" this figure, then adaptation can be much more difficult. What to do?
First, keep warm
In children with low body weight, the layer of subcutaneous fat is very thin, almost absent. In this case, it is difficult for babies to keep warm and the danger of hypothermia is quite real. The temperature of a small crumb should be measured at least once every 5-6 hours. If it is below 36.5 ° C, the baby needs to be warmed. The best way is skin-to-skin contact between mother and baby. Mom puts on an unbuttoned shirt, and the baby is placed on her chest. So the child's temperature and pulse normalize, and the mother's emotional state improves.
Second - we feed the baby by the hour
This is a necessary condition, because in children with underweight often the level of glucose in the blood falls below the prescribed level. This can cause sleep disturbances in the baby, a decrease in overall vitality. The best prevention of this condition is the frequent attachment of the baby to the breast. In the first days, the child should drink about 60 ml of milk per day. Then the amount of fluid drunk per day should increase daily by 20 ml per 1 kg of body weight until it reaches 200 ml per 1 kg of body weight. Those. with a weight of 2 kg, the child will need to be given at least 400 ml of milk per day (of course, the amount is divided into 8-10 doses).
Third - massage for appetite and general development
If the child has gained the cherished 2500 g, and the doctors (pediatrician, neurologist) give the go-ahead for massage, it's time to go through several strengthening procedures. Massage contributes to weight gain, as it whets the appetite even in such babies. It is carried out an hour and a half after eating. It is better to have a professional children's massage therapist massage the baby, or mother can master it on her own. Having lubricated the hands with cream, you need to carefully knead the baby's muscles according to the scheme from top to bottom - starting from the neck, then the back, buttocks, legs. At the end of the procedure - massage of the arms and chest.
Weight and Height Gain by Month: A Brief Overview of Up to a Year
Criteria for the proper development of the baby can confuse new parents. If it is difficult to figure it out, then you can always ask the local pediatrician for advice. The main thing to remember is that when calculating measurements, you should be guided by the initial data at the birth of the baby and only then calculate the individual monthly amount of weight gain and body length.
| 1 month | During the first four weeks after birth, the baby normally gains 600 g of weight, up to 3 cm in height. The nutrition scheme is compiled individually. The best option is a short interval between feedings (2-2.5 hours). For harmonious development, breastfeeding should be a priority. If the baby is artificial, the adapted mixture should be fed in the amount of 90-120 ml per 1 feeding. |
| 2 months | The weight gain of the baby in 2 months will average 700 g + 3 cm of growth. The breaks between feedings may already become a little longer, about 3-3.5 hours. During this period, you should not rush to wean the child from feeding at night, otherwise the weight will not grow so intensively. |
| 3 months | In the third month, the child gains 800 g and grows in length by 2.5 cm. The diet remains the same. Only in the case of artificial feeding can an increase in the interval between feedings up to half an hour be allowed. The volume of the mixture in this case increases, making up a portion of 150 ml. From the age of 3 months, the baby may be disturbed by colic, gas formation, therefore, a violation of appetite is often noted. |
| 4 months | By the end of the fourth month, the baby can gain up to 750 g and grow by 2.5 cm. The feeding regimen does not change. In the following months, the intensity of the increase in body weight will gradually decrease. |
| 5 months | At five months, the baby will recover by 700 g, and his height will increase by 2 cm. The weight and length indicators for this period double in comparison with the data of the child at birth. |
| 6 months | By six months, the baby adds only 650 g to body weight, and the increase in height is an average of 2 cm. The interval between feedings with the introduction of complementary foods into the diet increases to 3.5-4 hours. It is better to start complementary foods with hypoallergenic vegetable crops - zucchini, cauliflower , broccoli. Puree is given to the child in the amount of 1/2 tsp, the volume is gradually brought to 50 g over 5-7 days. By the end of the sixth month, complementary foods are replaced by one full feeding. |
| Seven months | At seven months, the baby's weight gain is 600 g and height increases by 2 cm. The child eats according to the usual regimen, mainly dairy food, and only one of the feedings contains complementary foods - gluten-free porridge or vegetable puree. It is necessary to accustom the baby to new dishes gradually, offering the introduced product in “drip” portions - from 1/2 tsp. at a time. This way, the danger of a sudden allergy (food can be excluded in time) or food intolerance passes. |
| 8 months | By the eighth month, weight gain continues, the increase is no longer so active - only 550 g, and growth continues to increase by 2-2.5 cm. The child’s menu can already be diversified with new types of cereals, fruits and vegetables. The first meat purees from rabbit or turkey are added to the diet, and the baby also gets acquainted with chicken yolk, which is tinyly added to liquid food. |
| 9 months | By the end of this month, the little man will grow 500 g heavier and grow by about 2 cm. The diet is already full and varied: the baby tries vegetable purees from several components, fresh mashed fruits are in priority, and a new product - cottage cheese, as well as kefir from permitted baby food . |
