My 12-week old son has been prescribed the above for reflux. He has never seemed to be in any discomfort but has always been a big vomiter and this seems to be getting worse. We're not yet 24 hours into the meds, but it seems he's bringing up even more of his milk than before. Might this be a reaction to the drugs? Has anyone experienced similar? Obviously the idea was that he'd vomit less not more...any words of wisdom/advice?
