sir my baby girl birth weight is 2.3 kg and now "she is 4 months 3 days baby now my baby weight is 5.6 kg ....is this good weight according to her age?

A. Hai !! Baby weight is good both according to age and birth weight.. Generally babies gain 400-900 gm per month ,by 5-6 months they double their birth weight. Baby doubled their birth weight ,so dont worry give exclusive breast milk or formula milk until 5 complete months ,start semi solids from 6 month onwards.
