my baby girl's birth weight is 3.2 kg... now she is 3.7 kg in 26 days... is the weight gain normal or under weight.?

A. It’s an absolutely healthy weight gain as we believe that the child should be somewhere around 500 g more than the birth weight in every month so your child is already gaining healthy weight so there is no problem with the current weight gain of your child seems completely healthy to me so is good enough as of your child’s age progressing
