#AskTheExpert sir, my 1.5 month baby girl vomits milk immediately after feeding. sometimes it is split milk and sometimes normal. it happens even after burping. she also passes gas with difficulty And cries after that. I am giving 0.5 ml neopeptine drops two times a day. also she cries uncontrollably especially at night as if in much pain. her belly button also protrudes when she cries.
