Question
My child has been crying and not eating much recently. What are the developmental indicators for a 15-week-old baby?
Answer
The younger the baby, the faster the weight gain. The first six months after birth are the peak period for a baby’s weight gain. In the first three months after birth, the baby’s weight can increase by 700-900 grams per month, sometimes even up to 1000 grams per month. After 6-12 months, the rate of weight gain slows down, with an average monthly increase of 300-400 grams. Of course, this is just a reference, as each baby’s growth and development is unique.
