Lo is 6 wks old, on similac tc, has diarrhea & bad colic. hes on buscopan and panado 3 times a day and doesnt want to settle (crying). hes not vomiting but does seem to be more comfortable upright. what can i do? is it reflux or something else?

Hard to say: Many 6 w olds are fussy. The expected peak of fussiness in a normal kid is around 6-8 wks with a decline as they become mobile (roll over). They also can be cow milk intolerant, lactose intolerant, have undiagnosed illness, etc. Without a review of their birth & post natal history, exam & maybe testing the origin of this fussiness is hard to determine.
