...do you watch them while they sleep, and make sure they are still breathing?

I don't know why I do this, but I do it every time. I also am pretty good at convincing myself that they're not breathing, and then being relieved when I realize that they actually are!

My daughter has a fever and a headache right now and we're both really worried about her. I keep staring at her chest to make sure it's moving, and then closing my eyes to listen to her breathing.
