Hey A.,
This will sound odd but I actually appreciate it when my kids come down with something mild. I look at it as a way for their immune systems to learn how to function. I let them run fevers, and I have never given them antibiotics for anything. (Although, just to clarify, we haven't necessarily needed antibiotics as we haven't come down with like... the plague or anything sooo...)
Kids pretty much run fevers and come down with stuff for the first 3-4 years of life. If her doctor isn't too worried, then I wouldn't be either. Although it is definitely difficult when they are sick... its best to let their bodies try to handle it on their own for the first few days (as long as symptoms aren't too bad and as long as fever isnt too high)....
She'll have an immune system of steel by the time she goes to Kindergarten! Hang in there!
