Reasons not to nap with baby brother. Number one.

I have two poorly children today. Ethan was ill throughout the night (injection side effects perhaps?) and Abbie started her day just fine. Less than an hour after I left her to school though I had a call saying she had suddenly developed a rash. It's all over. Took her to the Doctor and he is as baffled as me. No other symptoms and a raging red rash. Her biggest concern is that I'm keeping her off school tomorrow to keep an eye on it.
