Ryder had them on breast milk too. I actually always thought it was a good thing, because it happens so often, I just assumed that was the reason for his lack of colick. Lol, boy we do talk about everything on these forums don't we....discussing our childrens farts and exactly how smelly they are...lol.
Heather, I really would take him back though...maybe he does need soy based formula. It must be really hard hon, I wish you and him both well!
