What were the symptoms of it? I have a daycare boy who seems to constantly have very runny stools and it is very acidic (burns the poor guy's bum). The parents think it's from eating raisins and grapes or apple sauce but I don't serve him those things very often really. I'm thinking it might be a lactose intolerance. This has been going on for a very very long time. Any thoughts/suggestions? Links to some very good info that I can maybe pass on the the parents?
