Why human newborns are so fragile

Human babies are very helpless, mainly because:The brain is not well developedAnd, of course, there are some other reasons as well. Problems with the brain are the main problem.

Compared with other primates, it can be estimated that the gestation period of humans should be about 21 months, rather than about 10 months now. That is, about half of the years that should be spent in the womb are moved outside the body. Outside the body, the baby can continue to develop his brain rapidly without fear of damage to the mother's birth canal.

But at the same time, such babies are particularly weak and do not have the ability to walk independently. So all humans are premature babies. The reason is simple, if it is not born prematurely, then this fetus cannot be born, and then his large head will not be able to pass through the mother's birth canal at all.

Of all the mammals, only humans are in labor pains during childbirth, and the others give birth to their babies quietly, then clean up and take their babies with them. But since human erection, human beings have not enjoyed the pleasure of such simple childbearing.

In response to this contradiction, there can be two sets of solutions, one is to reluctantly squeeze out, and the fetus is forcibly squeezed out when it passes through the birth canal. The second is that the brain is not, that is, about half of the years that should be spent in the womb are moved outside the body. Outside the body, the baby can continue to develop his brain rapidly without fear of damage to the mother's birth canal.

But at the same time, such babies are particularly weak and do not have the ability to walk independently.

Continued growth in vitro is an important means for humans to cope with the large head fetus, which is why human babies need the longest nursing period, and they must rely on meticulous care to survive. That's why we say that it's because of walking upright that babies need to be fed with long-term holdings, not because babies need to be held upright.

Because of premature birth, human babies continue to grow as rapidly as in the womb after birth, especially the brain, which is the fastest expanding of all primates, and the obvious sign is that the bone suture on the skull has not closed, which is the fontanelle on the baby's head, and this bone suture does not completely close until a certain age.

The same is true of all other organs in our body, which continue to develop for more than a decade after birth, and do not basically complete their tasks until puberty, no animal grows so slowly like this, and almost a third of our lives are spent on growth, and this long growth consumption requires a lot of material and energy support from the mother.

So, human babies are very fragile compared to other animals.

Individual organ systems are not fully developed, are prone to injury, and do not have the ability to remove foreign bodies.

When I first came into contact with nature, I had no resistance to all kinds of bacteria, and I didn't have resistance myself 6 months ago.

I don't understand anything, I don't know how to say if I'm uncomfortable.

The baby is delicate, difficult, etc.

At this time, the child's internal organs are very fragile, and the body has not developed well, and sometimes there is no way to resist external damage. Be sure to handle it gently, keep warm properly, feed in time, and never go hungry.

Newborn children are relatively weak, and some things in the body are not fully developed, so this will lead to this situation, pay attention to nutrition, and do not take the child to some dangerous places.

This is because the body is relatively weak and the immunity is relatively low, so we must pay attention to the way we hold our children, pay attention to the surrounding living environment, and pay attention to safety.

Did you know that when babies are born, many mothers will do something that seems "stupid"?

When the baby is sleeping well, use your fingers to probe the baby's wild pure snort to confirm that the baby is still alive.

It may seem funny to outsiders, but this is a real worry and worry for many new mothers.

Of course, I think that as a normal father, even if you don't have postpartum hormones like your mother, when you see a soft baby of seven or eight pounds, you will take care of it carefully. ** I will also blame the mother who has just given birth to a baby for a month, and be careful of the revenge of the confinement.

So how fragile are newborns?

Some children were almost infected with pneumonia when they were born because they choked on a mouthful of amniotic fluid and were sent to the ICU;

When feeding, the bottle nipple should not leave air, because I am afraid that if I drink it, I will have flatulence, and if I get gas, I will have intestinal colic, and I will not sleep well with colic;

If you can't put it down immediately after feeding, you have to pat your burp, otherwise you will have bloating and your stomach will be uncomfortable;

When you fall asleep after feeding, you must watch it, because the stomach of the newborn is horizontal, and there is a risk of choking on the threat of life when a mouthful of milk comes back;

When you fall asleep, you have to put your little arms outside the quilt, otherwise you will be suffocated as soon as your arms are stretched out and covered by the quilt, because you won't tear the quilt off;

It can't be too hot, because the baby is easy to sweat and develop eczema, and the eczema will be very itchy, and it will not scratch it if it is very itchy, so it can only be difficult to cry, and it will not sleep well if it is too hot;

also coughs with milk from time to time, which parent can sleep;

It is also necessary to often observe the poop, whether there is mucus, what color, thin or thick, because the baby can't speak, and whether it is fed well can only be observed through daily diapers;

You have to cut your nails every other day, because the baby's metabolism is very fast, and it will scratch your little face ......

A newborn baby, eat to rely on the mother, sleep to rely on the mother, less sweating and less hiccups to rely on the mother, some fathers are busy with work, and when they go home, they have the courage to blame the numb who is always worried, it is too difficult to be a mother!

Women are weak, but mothers are strong! May all babies have no worries about speech and grow up healthily; May all mothers in the world have their wishes come true and live a long life; May parents live a long and healthy life and all the best!

The main reason is that the higher the animals are very fragile at birth, and the survival rate is relatively low.

Maybe this is a kind of law of nature, human intelligence is very high, so its ability to survive is weaker than that of animals.

Because it was only the beginning of evolution, it was relatively weak in all aspects of the body.

The pups are born through changes in respiratory function, and it is impossible for the fetus to breathe spontaneously by crying, so it is necessary to rely on the mother's umbilical cord for nutrients and oxygen. The lungs are useless before birth and can only contract in groups. When the fetus is bornAfter oxygen enters the alveoli, the lungs gradually change from solid to soft, and the lungs become important organs of the respiratory tract.

When a baby is born, the chest cavity can actively absorb oxygen and release carbon dioxide. When exhaled carbon dioxide passes through the throat, the gas affects the tight vocal cords of the throat muscles, and the vibrations are what we hear of a baby's cry. Other animals, such as orangutan pups or dog pups, do not cry at birth.

Many chicks cry when they are born. This indicates adaptation to the external environmentSince the vocal cords, respiratory tract and neck muscles are different from humans, the pups can practice breathing without crying at birth.

Why keep crying when your baby is born, because crying is the first way to bond with your mother. Scientific studies have shown that a baby's crying causes the mother to pay attention to food and love, and that the baby's crying changes the substances released by the mother's nerves to breastfeed and make the baby comfortable. Hugging while the mother is feeding gives the baby a strong sense of security.

And it does not exclude the psychological role of human beings, now every family will not have many children as before, every child is the baby of the family, so it will care for newborns extraordinarily. And will provide a variety of better living conditions. The reason why newborns are more vulnerable than other animals is due to the different physiological and psychological needs of humans.

Because this is the uniqueness of the species that belongs to humans, in fact, they are all about the same.

Because babies are not self-conscious when they are born, they cannot judge the dangers in the world, so they cannot protect themselves. And because newborn babies are relatively small, they are very vulnerable.

This is the law of evolution, because human beings can better protect their offspring, and if they can't, this may not be the case now.

Newborns have very low immunity and are susceptible to viral infections. Moreover, the bones of newborns are very soft, and there are often young children who have flat back of their heads because of the wrong way of lying in bed.
