Today we will reveal to you 15 amazing facts about kids. Which even their mothers may not know.

1. A newborn baby has almost one third more bones than in an adult - 300 versus 206. This happens because with age, some of them grow together.

2. At the moment of birth baby's head is a quarter total weight ... Until the age of 15-16, the body develops at an active pace - not comparable to the speed with which the head develops.

3. During the first few months of life children see the world in black and white colors ... The ability to see the full gamut of colors appears with age - when the eye develops enough cones, which are responsible for color vision. However, genetic failures also occur, and then the so-called color blindness develops.

4. Most newborns have clear eyes blue tint... This is because, at birth, the melanin responsible for pigmentation is still missing in the iris. At the age of 6-12 months, melanin is activated - then it manifests itself genetic eye color.

5. Up to about three months, children observe the world using peripheral vision... This is why newborns do not focus on the face of adults. And they can only see the details at a distance of 20-35 cm.

6. At the time of the birth of a child, his heart beats at a speed of 180 beats per minute. However, within a few hours the rhythm slows down to 140 beats. The normal adult value of 70-80 beats per minute is established only by the age of 12-16.

7. Chances of having a boy or girl the same - 50%. And yet there are always a few more boys born - and no one can say why. All the more surprising is the fact that the inhabitants of the country in which the hostilities are taking place, boys appear much more often than girls.

8. Child's blood type may not coincide with the blood group of the parents: there are often cases when a couple with I and II blood groups is born child III groups. Scientists have found that a child can have both the blood group of one of the parents and a "new" group, which is obtained as a result of the sum of the terms.

9. Found that fingerprints appear the fetus is still in the third month of pregnancy. And they remain for life.

10. Babies in the womb hear everything that happens "outside" and can react to the mood of the parent. Some newborns are not able to fall asleep in silence - because they used to constantly hear the beating of the heart and other noises from the mother's body.

11. According to recent studies, approximately from three months, children begin to recognize and prefer the faces of people of their own race. At the same time, in children around whom from the very early childhood there were people of different races, there are no specific preferences.

12. Approximately 10% of all newborns - left-handed, and this is manifested already in the first months of life. Interestingly, for twins, this percentage is even higher - 22%.

13. Newborn babies have congenital reflex diving and swimming... Thanks to the first, they instinctively hold their breath, plunging into the water - which does not allow them to choke. While in the water, the child makes movements with his arms and legs, reminiscent of strokes while swimming, and can hold out on the water for some time. However, this does not mean that they cannot drown. Therefore, do not flatter yourself, but rather look after the baby. He usually has no fear of water - and this can be used when in the future he will learn to swim for real.

14. Children start babbling at the age of six months. So far it is only "ma-ma" and "pa-pa". By the way, that is why these words - mom and dad - sound almost the same in different countries ah world. It is believed that the first monosyllabic, but meaningful children begin to pronounce words in a year and a half.

15. Surprising, but true. Premature babies are more likely to produce brilliant and successful babies.... Charles Darwin, Winston Churchill, Isaac Newton, Albert Einstein, Napoleon Bonaparte, Mark Twain, Jean-Jacques Rousseau, Pablo Picasso, Auguste Renoir and Johann Goethe were born prematurely. The opinions of scientists are divided. Some believe that premature babies it takes more effort to survive. Others suspect that such children simply retain their own special, different outlook on the world longer.

Nothing looks more fragile and defenseless than a newborn that you first pick up. But in fact, it turns out that in some way babies are very hardy and capable. Your newborn baby is able to get up interesting things that you can only dream of. But we managed to find out only thanks to the crazy scientific experiments- in any case, do not spend them over your child.

Fun fact: newborn babies can swim

One day, a group of scientists decided that it would be fun to dip 36 babies with their heads in cold water and check what will come of it. Surprisingly, instead of mass infanticide, they saw that the babies instinctively held their breath. They not only survived, but even laughed and smiled when they were taken out of the water.

Toddlers can do more than just hold their breath. Another experiment: the parents put the children in the water with their stomachs down and they began to kick and move their legs like a dog, which kept them afloat.

Studies have shown that babies can dive and swim, but this happens instinctively, and babies lose this ability by 6 months.

Small children can regrow their fingertips

Do not worry if your baby suddenly loses part of a limb. Dr. Christoph Allan believes that a child's body can regrow a fingertip if it is not interfered with.

Dr. Allan made this discovery with his little patient (the baby was eight at the time). The girl accidentally cut off the tip of her finger with a bicycle knitting needle and Dr. Allan could not sew it on, so he told her parents to just put the tip on her finger and maybe a miracle would happen.

A few weeks later, the girl went to see Dr. Allan again. She ignored the doctor's request, but the tip of her finger grew back. Further research only confirmed the fact that this is not an isolated case. The child's body is able to independently regenerate part of the phalanx if the damage has not reached the end of the nail plate.

Capturing a baby is equal in strength to that of a monkey

When a newborn baby wraps a hand around a finger of mom or dad, none of the parents in this touching moment asks the question - how high can I lift him until he unhooks?

Fortunately, scientists are thinking in this direction, and they found out the answer. It turned out that if you let the newborn take hold of your index fingers, the gripping force will be so strong that it will not fall when lifted into the air.

But don't try this trick at home, sometimes kids let their hands go in the air. Just take this already proven fact for granted.

Baby fingerprints fade quickly

Fingerprinting technology has allowed the fight against crime to take a step forward. Many cases are solved every day thanks to the fingerprints left at the crime scene. This problem would be solved if it was possible to train a group of toddlers and send them “on the job”. As it turned out, children's fingerprints disappear pretty quickly.

The experiment involved children under the age of 17. The subjects had to shake the bottle of alcohol, holding it with the index and thumbs, after which the prints were taken.

Scientists found that children's prints quickly disappeared, while adults remained. The researchers speculate that this is because there are more fatty acids on the surface of the skin of young children, so they quickly disappear.

Children can consume unlimited sugar

Sugar is metabolized differently in children than in adults. The child's body constantly requires sugar, which has a positive effect on development and can even be a pain reliever.

They were created to love sweets and can eat them without restriction. A product that contains more sugar than a can of Coca-Cola will be too sweet for an adult, but there is no such restriction for children.

The experiment consisted in the following: children were given a glass of sweet water and asked to say when it would be too sweet. At the end of the experiment, the smallest were given a glass of water so sweet that the sugar was no longer stirred, but even this was not the limit for them.

Newborns can crawl until they find a breast

Usually babies start crawling at 7-10 months. It turned out that this is because they have no incentive. If the baby is properly motivated, he can crawl until he gets out of the uterus.

The experiment was carried out on crumbs that were just born. The child was wiped off, put on the mother's stomach and did not feed. For the first 15 minutes, the children simply lay, then they began to suck air, and then they crawled to the mother's breast and sucked it.

So, you can make a newborn crawl if you leave it to itself for about an hour.

Babies act like a drug on the mother

If you have ever seen a mother holding her child in her arms, then you have seen a woman in the happiest and most peaceful state. And there is an explanation for this - the presence of the baby causes special chemical reactions in her brain.

From the first days of pregnancy, a woman's body produces oxytocin. We get this substance in the happiest moments (when we fall in love, have sex), and it gives us peace and well-being.

Mothers develop great amount oxytocin when they are caring for or touching the baby. Therefore, if mom Bad mood, it is enough for her to hold the child in her arms and everything will work out.

Newborns can eat as much as they want and not get fat.

You don't need to worry about your baby's weight. Newborns have a lot of brown fat (about 5% of total body weight), which burns calories at the speed of light.

It is this fat that helps the child not to die from hypothermia. When the temperature drops, brown fat begins to actively burn calories and generate heat. 85 grams of this substance can burn 400-500 calories per day.

If you have begun to envy children, then you are not alone. Some scientists are so jealous of the fat burning potential. child's body that they are trying to achieve the same results in adults, but so far unsuccessfully.

Children can speak dog language

Your kid may not understand everything you say, but he will definitely be able to understand some dog. Research into 6-month-old babies has shown that they can understand a dog's barking - even if they have never seen the animal before.

In the course of the study, the children were turned on recordings with cheerful and spiteful barking of dogs and at the same time were shown pictures depicting an angry or happy animal. Surprisingly, when recording with joyful barking, the children looked at the picture with a happy dog, and with an aggressive one, they chose the image of an evil one, since they instinctively understood the mood of the creature.

The fact that children could correctly match the tone of bark and the picture does not mean that they knew how to respond correctly. Subjects continued to smile at the sound of aggressive barking, so do not rely on their instinct for self-preservation.

The body of a newborn is able to grow a heart again

Scientists took a newborn mouse seven days old and cut off a piece of his heart. As practice shows, the government sponsors scientists precisely for such purposes. Incredibly, in just three weeks, the mouse's heart fully recovered and functioned absolutely normally.

Scientists believe that a similar function applies to all mammals, but this has not yet been proven. The luminaries of science, of course, are allowed a lot, but there is hardly anyone who will allow them to cut off a part of the heart of a newborn child.

Nature creates truly amazing defense mechanisms. Who would have thought that an ordinary baby is able to accomplish the almost impossible. And this, most likely, is not the limit. Let's see how scientists will delight us in the coming years.

Some parents tell their baby: "You are the light of my life." But did you know that if you were the light, you would fly around everything the globe 7.5 times per second! If you became sound, you could fly around the Earth in 4 hours! If we lived on Jupiter, our day would consist of only 9 hours. It's good that on Earth a day lasts 24 hours, because we need to do so much throughout the day! These are just a few fun scientific facts that may interest both the curious child and the adult.

What is Science?

Science is an organized and sequential study involving observation, collection of scientific facts, experimentation, verification of results, and explanation of natural and man-made phenomena. This is an area that enables us to better understand the world and create good things for the benefit of man and all living beings.

The Earth is between 5 and 6 billion years old. The Moon and the Sun are about the same age.
Our planet is composed mainly of iron, silicon and relatively small amount magnesium.
Earth is the only planet in the solar system with water on its surface and 21% oxygen in the atmosphere.
The surface of the Earth is made up of tectonic plates located on the mantle, a layer located between the Earth's core and the surface. This structure of the earth's surface explains earthquakes and volcanic eruptions.
About 8.7 million species of living organisms live on Earth. Of these, 2.2 million species live in the ocean and the rest on land.
¾ The Earth's surface is covered with water. When astronauts first saw Earth from space, they saw mostly water. This is where the name "blue planet" comes from.

The whole space is absolutely soundless, because sound does not propagate in a vacuum.
Venus is the hottest planet in the solar system. The temperature on the surface of Venus is 450 ° C.
The force of gravity changes a person's weight by different planets... For example, the force of gravity on Mars is lower than on Earth, so a person weighing 80 kg on Mars will weigh only 31 kg.
Since the moon has no atmosphere or water, nothing can erase the tracks of astronauts who set foot on its surface. Therefore, traces are likely to remain here for another hundred million years.
The core temperature of the Sun - the closest star to Earth - is 15 million degrees Celsius.

Facts about famous scientists

For a long time, people thought that the Earth was flat, that the change of seasons depends on the mood of the gods, and evil spirits cause disease. This continued until the great scientists proved the opposite. Without them, we would still be living in ignorance.

Albert Einstein was a genius, but his talents were revealed quite late. After the death of the scientist, his brain was the subject of numerous studies.
