The newborn is 7 days old and weighs 20 kg. Is this normal? What is the specific reason?

This phenomenon is not normal. A baby usually weighs 6 to 8 kilograms at birth, but it reaches 20 kilograms seven days after birth. This situation is generally caused by overfeeding. Some parents are afraid that their babies are malnourished and think that the more they eat, the faster they will grow. In fact, this practice is wrong. The baby has just been born for a week and eats very little. If the newborn baby is seriously overweight, there are generally the following reasons.

First, the baby is overweight and heavier than the average baby at birth. Some treasure moms are afraid that their babies will not absorb enough nutrition during pregnancy, so they are crazy to supplement all kinds of nutrition. By the due date, the fetus is seriously overweight, so the newborn will be heavier than the average baby. This situation is not pathological, so treasure moms don't have to worry too much. Because the baby's weight is also affected by genetic factors, it will gradually return to normal when the baby is older.

Second, parents' overfeeding leads to the baby's soaring weight. If the baby eats too much nutrition, it will turn into fat, and the more you eat, the fatter you get. Babies eat very little, especially newborns. You can't feed them too much milk powder, which will not only lead to obesity, but also lead to malnutrition. If your belly gets bigger, I'm afraid it's hard to lose weight in the future. When feeding the newborn, the baby should not overeat.

Third, the high fat content of formula milk powder will inevitably lead to baby obesity. At this time, the formula must be replaced. If the baby is born obese, parents choose milk powder with high fat content, which will bring great harm to the baby's health. Baby's milk powder should be chosen according to your own situation. Obese babies had better choose milk powder with low fat content, so that their weight will gradually return to normal.
