After becoming a mother, I like to exchange parenting experience with other mothers, and I feel that I am already very strong before the exchange, and I almost understand the baby's things clearly, but after the exchange, I found that I only knew one or the other.
So the following small changes in newborns, can new parents break through to the end?
First, many newborns are born 50cm.
I saw a post, the subject is a father, he asked: Why are newborns born 50cm?
The following netizen is very naughty, replied: Because this is the baby's appointment.
In fact, this answer is really no problem, it can really be said that the babies have made an appointment, the height of newborns at birth is generally 48 ~ 52cm, the average is not 50cm?
The two babies of the lazy mother's family were born with a height of 49cm and 50cm respectively, and the babies of many friends around them were almost this length when they were born.
We know that when the baby is born, it will be physically examined, measure height and weight, leave footprints for the baby, etc., but many newborns are 50cm, making it seem as if the nurse sister is lazy, but this is not the case.
Why are newborns so evenly tall?
In fact, this is related to the size of the uterus.
The uterus is about 50 g before pregnancy, and it is an inverted triangle of 7 to 8 cm long, 4 to 5 cm wide, and 2 to 3 cm thick, with a capacity of about 50 g in the middle, like a hollow peach.
After pregnancy, the uterus will gradually grow until the full term of the fetus, the uterus is about 20 times larger, that is, the uterus is about 1 kg at the time of the fetus's term, which is the length of the uterus is about 35 cm and the width is about 25 cm.
On this length and width, the fetus baby wants to grow more than a lot of long ah, so in order to match this length, the fetus will generally look at the dish, try to control their height of about 48 ~ 52cm.
This length is longer than the uterus, how can it fit the baby? Don't forget. Babies are very smart, and when they are in the womb, they know how to shrink their hands and feet and put them on their chests, so that they can try not to hold up their mother's womb so hard.
So we just saw that in fact, in about 31 weeks of pregnancy, the size of the fetus is almost the same size as when it was born, and the main task behind it is no longer to grow tall, but to gain weight, and now we know why the baby's weight has increased so fast after the third trimester!
Second, newborns are born with poor vision and cannot rely on their eyesight to recognize their mothers.
In the past, it always felt very magical, the newborn baby can recognize which is the mother, others cry when they hold it, but as long as they put it back on the mother's hand, they can stop crying immediately, is the baby so small that it will recognize people, and it can be seen which is the mother just born?
To recognize people is to recognize people, but not to see with the eyes, not by the strength of vision, but by the smell of milk on the mother's body, the familiar heartbeat of the mother and the sounds that have been accustomed to hearing in the womb.
Because newborns have very, very poor vision!
How bad can it be?
Although the newborn baby will be more sensitive to light and color, but can only see 20 ~ 25cm, 20 ~ 25cm is so close, it is already a face-to-face distance, even if it is not far to see, the baby will not adjust the focal length of the eyes, so it is vague when looking at things. In other words, a newborn baby, even if you hold him and look at him face to face, he can't see who you are. Well, the baby is two months old, can see 50 ~ 60cm, but also learned to adjust the focus of the eyes, now see what is much clearer than when he was just born, but in fact, it is still blurry. The baby is three months old, can be farther away, now you can see 3 to 4 meters, to the baby four or five months can see 4 to 5 meters, the vision is getting better and better, you can easily recognize the mother.
So, did you know this when your baby was born?
Third, the baby's body temperature is higher than that of adults
When we usually have a fever of 37.5 degrees, the doctor will tell us that the fever is low, but when the baby has this temperature, the doctor will tell you that this is very normal.
That's the double standard!
Your baby's body temperature is indeed higher than that of adults.
Mainly because the baby has just been born, the nerve center that regulates body temperature has not yet developed well, so this also leads to the baby is easily affected by the external temperature, so the baby will be afraid of cold, and the heat will be afraid.
So when we measure the baby at 37.5 degrees, don't worry too much, give the baby more milk, and give the baby some water appropriately.
Fourth, the baby's weight after birth will not only not rise, but will also decrease.
It is said that the baby in the month is the same every day, but I did not expect that the weight of the baby did not rise after birth, but also decreased, is it because of insufficient breast milk?
It doesn't make sense, the milk powder baby also lost weight.
In fact, the weight loss of newborns after birth is also a normal physiological phenomenon.
In fact, the baby is born with physiological edema, weight loss is because of the discharge of the fetal stool and urination accumulated during the fetal period, but also the drainage of edema of those water, so that the baby's weight will drop some.
The general decline is about 5% to 7%, usually not more than 8%, if more than 10% is abnormal, parents must take the baby to see a doctor in time.
Normal weight loss does not require any worry from parents, usually this situation will be restored about 1 week after the baby is born, and the weight after that is normal.
The baby in the month is the fastest growing rate in this year, as long as the milk is sufficient, the baby will really rub up, the normal month is 2-3 pounds, more than 4 to 5 pounds.
If the baby's weight gain in a month is less than 600g, it is generally because of insufficient milk, the baby is not full and hungry.
I didn't expect that there will be so many little secrets on the newborn's body, if you don't say it, I believe there are many new parents who don't know it.
