At birth, my baby was 3.25 kg and now at 7 months he is 6.8 kg. is it normal weight gain or less. he appears very lean and thin.

A. Just one less not more than that because if you look at it if I should be 3.5 kg more than the birth rate child is lacking with 200 g only which is okay it’s not a problem with proper food that you give to the child the child is going to gain better
