M.K.
I agree with the response saying it could be impetigo. I believe that is caused by strep. My son had hand foot and mouth, and I think it would be obvious spotting everywhere, not just her face. My son had lots of blisters on his hands and feet, a couple spots on his face, and some in his mouth. They didn't get crusty until after his fever broke (it was really high) and a few days had passed. I would take her in.
