Question
The newborn weighed 8 jin and 2 liang at birth and increased to 12 jin and 8 liang after 42 days. Is this weight gain within the normal range? What are the possible reasons for weight gain?
Answer
Hello! The weight gain of newborns is indeed quite rapid. However, whether it is normal depends on whether the child’s height is growing in sync, and a comprehensive assessment should be made based on the parents’ height and hormone secretion status. In the first month after birth, there is a significant change in both height and weight, with an average weight gain of about 3 to 4 pounds, which is within the normal range. As long as the baby has sufficient food, good sleep, and normal activity, it indicates that the baby is growing healthily.
