Hello My baby is 1 month and 8 days old at the time of birth his weight was 2.7 and now his weight is 2.9 how much weight should be after 1 month? and what can I do to gain his weight?

A. Its 500 gm min that a child should gain in a month so your child hasn’t gained anything if u look at it practically and then your child is too underweight u should check with your doc once so that u can start with powder milk for the child
