A while back DD had a bad case of diarrhea. It just wouldn't clear up after almost a week. The doctor suggested on a whim that sometimes a stomach virus can trigger a milk allergy, and to try and switch her to soy formula. We did, and immediately she got better and has been great ever since. But I don't really know if she actually had a problem with the cow's milk formula, or if the virus was ready to clear up on it's own. Or even if she did have a problem, maybe it has passed. Now it's time to start her on solids though, and I'm a bit concerned. I'd like to introduce oatmeal first, to avoid constipation which has been an issue. But, I'm wary because of the milk issue. Also, I'd like to introduce yogurt at some point, but don't know if that's such a good idea either. And does anyone know if there are lactose free yogurts out there? What's everyone's opinion on what I should do about starting the solids? Thanks so much.
