My first thought after reading your post (before reading replies) was hand foot and mouth. A friends dd had it just last week so if you're in wa it is possibly going around its pretty contagious. But not really as terrible as it sounds (usually) my older 2 had it when dd2 was about 8months and she didn't even get it, they only had a few spots for a couple of days/week. Hope you find out what it is and she's better really soon
