My 5 weeks baby is vomiting after every feed. Also releasing Gas most of the time. My feed time is 5 to 10 minutes with intervals of 2-3 hrs. Consulted paediatrician and was suggested with Domstol with dosage of 0.5ml and colic acid with course of 2 weeks but still same.So revisited and was given Domstol again with dose of 0.8 ml.Using since 2 days but don't see any change of vomitings. Any suggestions please. Baby birth weight is 3.5 and now it was 4.
