Hi J., my son had spots - raised bumps that were a little wart-like. They looked like pimples, and at first they were just on his belly and neck. They didn't go away, but they didn't bother him, so we didn't worry. Then several months later, he got a few on his face. So, (of course) he would pick or scratch, and they got red like pimples would, but after the redness went away, the bumps stayed.
I finally took him to his pediatrician. She told us she thought it was some sort of wart, and sent us to a dermatologist. The dermatologist told us they are a type of wart, caused by a virus, and can take over a year to clear up on their own. Adults are no longer able to get them; we at some point become immune. I guess everyone gets the virus, but not everyone gets the bumps? I had never seen them before...
Anyway, it is very contagious, so your daughter should not bathe with siblings. If it's too late, then it's too late... The dermatologist gave us some expensive cream (Aldara) and you only put a pin drop of it directly onto the wart every 2 days and over the course of about 2 weeks (if I remember correctly) they clear up. If they give you single dose packages, to make the medicine last longer, poke the package with a sterilized pin to get the cream out, then refrigerate it for the next dose. The docs told us that one, not just us being cheap!
Best of luck to you!
