my daughter projectile Ved for just over a year and it was acid reflux....she was on a variety of different meds and things are finally better although she has been diagnosed with a boatload of GI issues...couldn't hurt to talk to doctor and maybe see a GI...ifs its reflux, its an fairly simple fix. Good luck and HUGS! Its horrible I know, I went through it for over a year and was in a constant state of anxiety. Hang in there!
