Will figuring it all out make the reflux go away?

My YDD is mspi and egg intollerant. She is 14 months and her reflux seems to be getting worse not better with age. I recently began medicating her (just a couple of weeks ago) and it seems to be working. We are also waiting to see a ped gi. When she was younger her symptoms of getting soy, dairy or egg were reflux otherwise she didn’t reflux and had no symptoms of allergy. Now she just has reflux all the time w/o meds and I can’t figure out a trigger. The zantac is working well for her so far but I would rather eliminate the need for meds if I can keep it controled with diet.

I guess he could be developing another intollerance or could there be some other reason for the reflux? My ODD also has intollerances so that bit I’m quite familiar with but I don’t think she ever had reflux so I haven’t ever managed that before.
