Hi, my son is 2 years old and has been throwing up for a whole year now! He was a very gassy baby. He has been on acid reflux (baby zantac medication off and on) but still the vomiting continues. He had a Barium Swallow test which confirmed that it wasn t due to any structural problems. I have tried liquid diets, I mash up his food and give him a balanced diet ( 3 meals and 2 healthy snacks in between) and I even tried soy & rice milk b/c I find that when he s teething he cannot tolerate milk. When he throws up the milk comes up kurdled but his vomiting is not only milk it is very random. Please help!!!!! He has not gained any weight for the past year now. I was told that maybe he has a weak spinchter .. but I do not want to speculate anymore. It s hard to watch him go through this.
