Hi, My son was birth weight is 1.850kg he is bron at 37 week of my pregnancy now he is 3.500 kg. It's normal weight?

A. So practically a child has gained 15 to 1700 g in one month so that is an exceptionally healthy weight usually said that the child would gain about maximum of 1 kg your child has gained much better than that which is good for the growth of your child
