Over the past few years I have been eliminating different foods and drinks from my dd's diet. She no longer drinks milk she does have dairy products I just don't give her milk to drink she seems to have trouble w/ it and she refuses soy, however I have been considering giving her skim milk to see how she does. It took forever to get her to drink something other than milk she was about 5 when she started drinking juice I have since transitioned her to the Motts for Tots. My store only carries three flavors Apple, Apple White Grape and Fruit Punch. I for the past six months I have been experimenting w/ the three flavors around June or July she had been belching really badly and very fowl smelling. So I cut alternating the flavors an stuck w/ just the apple juice and no problems for a couple of months, then I switched to the apple white grape for the same amount time w/ no trouble and since we had a trip in december and christmas holidays I didn't want to jeopardize them by trying the fruit punch so I just got around to trying it and w/ in one day she was belching again we finished that bottle and have since gone back to just apple for right now. My concern is whether I am dealing w/ just reflux or possibly an allergy. How can I determine what is causing this and where is the best place for me to get info on things to stay away from if it reflux.
