38 and 40 weeks of pregnancy are full term, how is the difference between the baby born? Don't underestimate the difference of 2 weeks

Text/Good Pregnant Sister

Yesterday, someone in the mother group asked such a question: I am now 36 weeks pregnant, because the fetal position is not correct, so I must have a caesarean section when I am born. Considering that morning and evening are all caesarean sections, I want to wait for 38 weeks pregnant to go to the hospital to give birth.

After all, the baby stays in the stomach all day, always worrying about what accidents occur, it is better to quickly unload the goods to be at ease. And the third trimester is really tired, how to sleep is not comfortable, pubic pain to doubt life.

Therefore, I consulted with my mother-in-law and asked her to rush from her hometown in advance and go to see a good day of giving birth to a baby. As a result, the mother-in-law has been advising that "the child grows in the womb for one more day, which is equivalent to ten days outside." ”

I don't understand, isn't more than 37 weeks full term? Is there really a difference?

In fact, after entering the third trimester, pregnant mothers are more nervous in their hearts. After all, although there is a due date, the fetus is very willful, and often will not be born on the same day.

Therefore, some pregnant mothers who plan to have a caesarean section do not want to wait for the moment when the melon is ripe and want to see the baby in advance. But it will be the same as this pregnant mother, with similar doubts.

So 38 weeks of pregnancy and 40 weeks of pregnancy are full term, how will the baby born be different? Today, let's briefly nag.

What is term delivery?

Full-term delivery refers to the first day of pregnancy from the first day of 37 weeks of pregnancy to the sixth day of 41 weeks of pregnancy, during which babies born are all full-term births.

However, due to 37 weeks and 0 days to 41 weeks plus 6 days, spanning 5 weeks, the maturity and prognosis of the fetus are different. And the incidence of maternal and neonatal adverse outcomes was different, in a U-shape, with the lowest point being about 0 days to 40 days at 39 weeks plus 6 days. Therefore, many medical experts recommend subdividing full-term pregnancy into:

37 weeks + 0-38 weeks + 6 is called early term birth;

39 weeks + 0- 40 weeks + 6 is called full-term delivery;

41 weeks + 0- 41 weeks + 6 is called late term delivery.

That is to say, after 37 weeks of pregnancy, if the baby can't wait to come out, it is also OK. However, babies born at 39 weeks– 40 weeks and 6 days may be healthier than babies born in the early and late term periods, and the probability of maternal risk at delivery will be lower.

So what is the difference between a baby born at 38 weeks and a baby born at 40 weeks' gestation?

Height and weight

Except for a very small number of overweight babies, under normal circumstances, babies born at 38 weeks of pregnancy are about 45 cm - 48 cm tall and weigh about 5 kg - 6 kg. Babies born at 40 weeks of pregnancy are mostly about 50 centimeters tall and weigh about 6.6 kilograms.

Appearance

Compared with babies born at 38 weeks of pregnancy, children born at 40 weeks of pregnancy will have a slightly larger head circumference. Since the fetal fat and fetal hair are cleaner and fatter, the baby's skin will be fuller and smoother.

Functional development of the lungs

Because the lungs are the latest to develop of all organs, they may not have finished developing by the time they are 37 or 38 weeks pregnant. Your baby's lungs are relatively weak and the first cry is smaller.

In the 40-week pregnancy, the lung function development is more mature, the crying will be louder, and the resistance is relatively strong. And you may be born with big eyes.

Finally, I would like to say that according to the theory, it is better to have a baby at 39 weeks of pregnancy - 40 weeks of pregnancy. But if your physical condition does not allow it, don't mind too much, after all, the safety of both the mother and the baby is the most important.
