My daughter is 3 and half months old..But her weight is 5 kg.. How could I improve her weight?

A. Mam you have to check how much as your child gained in these 3 1/2 months on the basis of minimum gain of 500 g in a month so you’ll have a fair idea that your child should be somewhere around 1750 g more than the birth if that is there then this is healthy otherwise you can give powder milk
