Daughter is sick

My daughter is sick again. She has a rash on her face but I don't know where she got it from. She's been teething a lot lately but I'm not sure if the rash is because of her teething. My wife wants me to take her to children's hospital tonight. I'm hoping it's nothing serious although my wife checked her temperature about a hour ago and she said that my daughter has a temperature of 99.5 I'm no doctor or physician but I think it's normal for most baby's to get a temperature once in a while. I heard that getting a temperature is the body's way of fighting off a sickness. At least that's what our pediatrician told us about our son Ethan before. Well, at least I don't have to work tomorrow morning. I'm stuck on graveyard and I start tomorrow night. I get to sleep in tonight.
