My baby girl is gaining weight slowly, but doctor says if she is active then fine. Her birth weight is 2.7/kg.. she is 5 kg in 5 months. is this normal.

A. But that is completely alright if you practically look at your child has almost doubled the birth weight by completing the age of five months which is good enough and if you’re not satisfied then you can start giving formula milk to the child for better weight gain at least twice or thrice in a day along with breastfeeding
