Poor kiddo

- no fun to have a yucky tummy!
First, what were you feeding when this all started? And has it happened w/ multiple foods? Have you tried raw at all? Probiotics?
I'm not a big fan of RC either, but if/when all else fails - prescription type diets can sometimes work miracles with protracted issues.
If you want to try a probiotic, I'd recommend the one from Natures Farmacy.
Any signs of acid reflux or anything btw....?
