What's the difference between a baby born in 5 kg and a baby born in 8 kg? Is the fatter the newborn baby, the better?

Compared with 5 kg and 8 kg, as parents, they all hope that their babies will be heavier and chubby when they are born. Naturally, they prefer a baby of 8 kg. What's the difference between 5 kg and 8 kg newborns?

1. The definition of newborn is different: low birth weight baby &; Fetal gigantism

① According to birth weight: those who weigh less than 5 kg at birth belong to low birth weight infants, mostly premature infants; Those who weigh more than 8 kg at birth belong to macrosomia, mostly caused by gestational diabetes or improper diet.

② According to gestational age: The gestational age of premature infants is 28-37 weeks (including 28 weeks), and most of them weigh less than 5 kg; Newborns with overdue pregnancy were born at ≥42 weeks, also known as "over-mature babies", and generally weigh more than 8 kilograms.

2. Different feeding after birth

①? Newborns weighing less than 5 kg are difficult to raise, because the development of various organs of the body is not mature enough, and the ability to breathe and suck spontaneously after birth is relatively weak, which requires special care. Milk quantity per time 10-30 ml.

(2) The macrosomia weighing more than 8 kg is a high-risk newborn, and some of them are caused by gestational diabetes of pregnant mothers. Although they are heavy, they are actually immature and have great problems with blood sugar metabolism. They are prone to hypoglycemia within 24 hours after birth, so they need to monitor blood sugar and feed sugar water at birth, and the amount of milk is 30-50 ml each time.

3. Different delivery methods and stages.

①? For pregnant mothers, newborns born at 5 kg are more likely to give birth naturally, and the fetal head and pelvic cavity are easy to be symmetrical, so the labor process is relatively short;

(2) For giant babies born at 8 kg, most of them are because the fetal head is too big to descend to the pelvic cavity normally. The process of natural delivery may lead to dystocia, and finally the probability of natural delivery to caesarean section increases. Therefore, if the estimated fetal weight exceeds 8 kg, the general doctor will not recommend natural delivery.

Is the fatter the newborn baby, the better?

The answer is yes: of course not!

The newborn's weight is preferably about 6 kg, which is beneficial to natural delivery and can also reduce neonatal complications; Therefore, it is not that the fatter the newborn baby, the better. If the baby weighs 8 kg at birth, most doctors recommend caesarean section, even if it is delivered naturally, it is very likely to be transferred to cesarean section.

As parents, as parents, all want to raise a fat baby, but it is not necessarily a good thing that the baby is too fat:

First of all, it will bring a heavy burden to pregnant mothers during pregnancy, and it is difficult to adapt to both movements and physical changes; Secondly, the overweight fetus is likely to cause pregnancy complications for pregnant mothers and bring more risks to delivery; Finally, macrosomia is prone to complications after birth, such as hypoglycemia and dehydration.

However, new mothers don't have to worry too much about the problem that newborns weigh less than 5 kilograms or more than 8 kilograms. Newborns will get an "Apgar score" at birth. As long as the score is reached, the baby does not need special care.
