My dd 3 yrs old came home from nursery with a high temp yesterday. She did not sleep well last nigh and was sick a number if times. She has not been sick anymore today but only really had liquids. She has a spotty rash all over her body and flushed red cheeks. She is complaining of achy arms and legs plus a sore throat and has a white coating on her tongue. She is also really sleepy and has dozed pretty much all day? Should I take her to be checked?
