So my son for sure has acid reflux I have to wait to see if anything else showed up. He's already taking Zantac for it. Any other babies have this? And what have you seen helps best. Any certain foods I should cut out? I've had acid reflux and really bad GERD at that. I feed my son very healthy things. His father does not. He has a Wheat allergy so he's gluten free. Just wondering if maybe I should cut out anything else that may be causing discomfort.
