I am the kind who told my daughter, "You're not going to throw up." 20 seconds later, she threw up.
That was yesterday morning, 6:45 am. By noon or so, she was feeling a lot better and hasn't thrown up since. No fever. (I'm putting all this in for my mom, who will want to know.)
By the way, I know how to get vomited tomato out of the carpet.
