gerd from birth ?????

My daughter started vomiting just three days after she was born.She was solely on mother's milk for first six months .even then she vomitted more than once .Upper GI was done to see any abnormality.The radiologist thought she had hiatus hernia .But the gastoenterologist ruled that out after performing endoscopy.We did an allergy panel .She has no alergy to any food.She improved a little bit after she was a year old but gets worse now and then.She can't take orange juice.She thows up almost always after taking it.She also thows up with milk frequently though she has been drinking milk until she was 5.I stopped milk completely except on occasions for the pat one year.She is sometimes okay with milk ,sometimes not ok .She is 6 years now.She has been vomiting frequently for the past 2 months.Also complaints about stomach pain after eating.Mostly feels hot right before vomoting. I don't want her on antacid.Can someone please suggest a homeopathic remedy.
