hi doctor...my son is 11.5 months old and he is only 8 kg while his birth weight was 3kg...please suggest what to do for his weight gain...he doesn't take milk other than breastfeeding

A. Hello mom babies tend to to double their birth weight by the age of 4 to 6 months and then it takes about 1 year to triple it . At the mom your milk is best along with the solids to him , animal Milk should be given only from the age of 1 year onwards
