My female baby was born with 2.66kg and she is 1 month old now and her weight is 3.05kg. Is it correct weight or underweight which requires any medical attention?

A. Actually child should gain 500 g in a month your child has only gained 400 so it’s okay in the next month also check if your child does not gain 500 g then start with formula feeding along with breastfeeding like how many numbers of breastfeeding you are giving just replace two with formula milk
