My baby is 2 months old and recently I consulted him to a pediatrician and my baby was having distended abdomen which was not hard because of trapped gas because of which he was farting a lot and he does excessive crying and he doesnot pass stool for 4 days and his weight is 4.4kg so because of the complains doctor prescribed coligo drops and as well neopeptine 9 drops for 15 days. My doubt is should I give neopepsin or coligo which one would be better. I gave neopeptine and after giving that he vomited twice. I am really concerned and confused what to do
