My baby has Scarlet Fever. He came home Friday afternoon complaining of a sore throat. 1st time ever too. Well, we did medicines and wasn't helping. So this morning I decided I'd take him to the doctor. Got him there at 2pm and the doctor tells Ryan to open up and say 'Ahhhhhhhh', and he did. And the doctor said instantly that he had strep throat with scarlet fever. Ryan has a rash on him from head to toe. He gave us a prescription for penicillin, he has to take it for 10 days.
