My baby is 4 month 2 days old she is 5kgs ..her birthday wight was 2.7 kgs is she underweight? what should I do..because she vomits a lot.

A. dear Mum, weight of 5 kg is a normal weight for your 4 months old baby considering a birth weight of 2.7 kg. it is normal for babies to vomit at this age. burp baby after every feed. keeping the head and chest at a level higher than stomach helps to reduce the chances of vomit.
