GERD-Anyone with kids that have it?

Does anyone know of a remedy that might help me? My daughter 8mths has GERD. The docs have tried several different meds to help her but nothing works. Ive tried Gripe Water and gas drops. She sits up when she eats and everything! They dont want to do any tests yet because shes so young. She even throws up her baby food. I don't mean she spits up a lot, i mean she projectile vomits ALL DAY! Shes gaining weight so at least shes getting what she needs but it it literally non stop. I have to wrap her in blankets on the way to school just so she wont soil her clothes before we even get there. At School (daycare) she gos through about 5 outfits a day. This is even with bibs on. Shes a happy baby so its not hurting her to bad. Anyone have this problem? What can I do to get the spit up to go down? Thanks.
