Babies should be thinner in the first few days after birth. This is normal because babies have extra weight to support them at birth until they drink breast milk. Colostrum is a nutrient-rich viscous substance, which is produced by the mother's postpartum breast. In the first few days after birth, newborns sleep for a long time, have weak sucking power, and have less time and times to breastfeed. In addition, at the beginning, the mother's milk secretion is small, and the nutrition can't keep up, which will lead to slow or even retrogression in weight gain.

The baby's weight increased rapidly in the first few months. It is not common to say that clothes are getting smaller without looking at the baby's length. Especially in the first three months, you will gain about half of your weight, reaching one or two per day. A few days ago, some newborns lost weight, because the baby has a process of absorption from umbilical cord to gastrointestinal tract. Don't worry too much about losing weight the other day. When breast milk is sufficient, the baby's weight will rise again. Yes The slight fluctuation of baby's weight is related to the baby's weight and feeding condition, and also related to whether the baby has defecation or not. If the baby is satisfied and healthy, parents should not worry too much about the slight fluctuation of weight, but if the weight loss lasts for a few days, it is necessary to carefully investigate the reasons.

Some parents are so worried about their baby's growth that they have to weigh their baby almost every week. Sometimes the baby doesn't gain much weight, and the family will worry about whether the mother's milk is not nutritious or not. Look at the baby's weight gain should be based on the average growth of 4 weeks, not on the weekly growth. Baby's weight gain fluctuates every week. For example, when you are sick, you may lose weight, but you will recover soon after you get sick. As long as the average weight gain is normal within 4 weeks, it is normal.

Once breast milk is ingested, the baby should begin to recover his lost birth weight within two to five days after birth, from 10 to 14 days. During this period, you will gain at least 15g every day. If the newborn's weight drops by more than 7% in the first few days after birth (for example, a 6-pound newborn loses more than 0.45 pounds), or it takes more than two weeks to regain its birth weight, please see a doctor, who may recommend taking supplements. Babies fed with formula milk powder are less likely to gain weight than those fed with breast milk. Bottle-fed babies are more likely to get fat, because formula milk is more concentrated than breast milk, and parents often want their children to finish drinking milk. Don't push. Children turn their heads away and are usually full.
