My 5 year old daughter (45 tall, 46 pounds) has had a fever for the last few hours. It was 102.7 three hours ago. We gave her children s acetaminophen, a lukewarm bath, and it dropped to 101.7 then, but it s back up to 102.7 now. She has a sore throat and chills and seems very tired. She s vomited one time, but it seemed to be mucus, although she s not coughing. Should we take her to the ER?
