Anyone else fighting sickness since starting school?

We started school late August and my girl has been a mess ever since. First it was a seasonal allergy flare up. Followed by strep throat. Then a round of sinus infection. Next an ear infection. And now again, round two of strep throat. She's now started her fourth course of antibiotics in about 10 weeks time.

I really thought through all of her daycare exposure she'd have an easier time with public school. Today is her first day absent, and she's absolutely miserable. The doctor said to expect a lot of strep through 2nd grade.
