We know that Linnea has some severe food intolerances including dairy. Yesterday, before I could stop her, she had a couple of sips of Amelia's milk. Since then she has had five or six episodes of diarrhea. At first I just thought it was the milk, but can such a small amount (literally a sip or two from a sippy cup) cause so much trouble? She's eating just fine and acting just fine. I'm trying to figure out if I need to keep her away from other kids. The girls spend two afternoons a week with a couple of other kids.
