My Dd had a bout of diarrhea a couple months ago and the doctor said it was a virus. However, the doc said it could trigger a milk intolerance and so we switched her to soy. She's been fine on soy, and I don't know if she really had a milk reaction. But we started her on yogurt today, whole, plain, organic. I'm just curious what reactions if any I should look for? She has eczema, so that might flare. And I know about looking for diarrhea, but are there more subtle signs out there? LIke gas, tummy aches, etc.?
