#asktheexpert weight of 4 months old girl child 5.5 kg ,is it okay?

A. Hello good morning !! Baby's birth weight..?? According to age baby present weight is fine, generally they increase 400-800gm per month, double their birth weight by 5-6 months.. Compare and check present weight with birth weight... Until 5 complete months exclusive breast milk or formula milk is suggested,from 6 month onwards start semi solids, check suitability before introducing new food items..
