So my daughter had croup alkost two weeks ago and has been perfectly fine since. She was playing all weekend and we even stayed out of the rain today. She ate her dinner and everything then when she went to bed she started to feel unusually hot. I know she will get warm while sleeping but I decided to check anyways and her fever was 104.5 should I be worried? She's responding to me moving her but her breathing is fast and hard... she's never got a fever out of nowhere like this. Am I over reacting? Will she be okay?
