I've noticed a couple of times when Rileigh is sleeping that she seems to dry heave. That is the best way to describe it. She does like 2-3 heaves and then she is fine. I always run to her to try to lean her forward so that if she does throw up it comes out. It kind of concerns me and my friend mentioned today it could be reflux? I'm asking the doctor tomorrow about this but it is so strange. Have you ever experienced this with your kid/s?
