my baby is a premie with 1.9kgs weight.. now he is 7kgs and 70cms height.. but my baby looks too skinny.. he doesn't look like a 7 month old baby.. should I consult my doctor about body growth

A. The Weight and height of your child is perfectly normal I don’t think so you need to consult your doctor bring a premature child your child has taken proper weight and growth as per the age so just continue feeding in the similar manner things will be better with time but as of now also they are good
