My dd had CP at 12 months as well. It was miserable, but she had them everywhere! We didn't realize until she was done, that her molars also were coming in, poor thing. We did lots of aveno baths and nursing. She has a few scars on her back. It seemed terrible at the time, but now we're happy she had it naturally and early. Got it out of the way and one less vax we have to fight about.
