My little guy was born at 36 weeks. He has been struggling with reflux (per his pediatrician). We have switched to Alimentum formula and tried Zantac and now Nexium for his reflux. He still seems to gag and chew on reflux all day and then at least one evening feeding he vomits everything up within 15 minutes of finishing his feed. He doesn't vomit any other time of day, spits up very little, burps well. He doesn't eat any extra at the feeding where he vomits, I still hold him upright the same amount, just boom vomit everywhere. Anyone else?  What helped your reflux? When did it get better?!
