#asktheexperts My baby is born in 32 weeks and weighed 1.5 kg. Now he is 52 days old and weighs 3.1 kg. He has been facing gas and colic issues from the last few weeks. I give him colicaid drops and himalaya bonnisan thrice a day. I also keep him in 45degree position while sleeping and keep him upright for burping after every feed for 30 minutes but the problem remains the same. Nothing really helps and he sleeps uneasy. ( he is exclusively formula fed). I feed him pro Nan.
