M.D.
My son 16 mo old had reflux from day one. As he got older he started doing the cough & vomit thing. Found out thru a ped. pulmonologist that he also has respiratory stress disease. It starts as a dryish cough then he gags & throws up. But he's fine & happy after. He snored & was wheezy sounding. Also found out thru an allergy test that he's allergic to milk. Ugh!! I wonder if a child can develop the reflux at 6 mo? Maybe keep track of what he eats & see if its linked right before the throw up. I know the season change also causes the itchy throat which may be causing the coughing & eventual vomit.
