M.S.
Hi my daughter had it bad and still has some spitting up at 2. It is acid reflux, she has no allgeries. Have you tried uping his meds. Has he gained weight? If yes then he needs his meds. uped. Get him weighed...every little bit counts. Also, work are recently worked for me is giving meds. at least 30 mins. before a feeding. I never did this until I saw a GI and he told me that I had to and it worked. Have you seen a GI, I wait until my daughter was 18 months and that was tooooo long. The GI also asked why I waited so long. It can only help. If you need a good one I've got one. Hope this helps.
