Yea, it never hurts to just take her in and get her checked.

It could be something as simple as roseola. Lydia had this last June...4 or 5 days of a fever followed by a non-itchy rash for a couple of days, and then all better.

I hope your sweet little Hannah feels better ASAP and back to her normal giggily self.
