Mother of the year, that's me!

A couple of weeks ago both of my girls were sick... the big girl got better but then got a rash. The little girl kept feeling bad off and on...
After two weeks of the rash, which I was certain was a viral rash, I finally took her to the doctor...only to find out they both have Strep!
They have both had strep a million times and have always had high fever, head ache, etc... I would have never guessed they had strep.
I'm not sure if I feel worse as a parent for not getting the rash checked out sooner or as a school nurse for not thinking it looked like a strep rash... The doctor did make me feel better...
Her words were "never underestimate the power of strep...it never looks like you expect" Noted....
The funniest part of this has been that the doctor told the girls they had to stay home from school today. They both felt fine and had been going to school with it already but she said stay home...
The big girl cried, fussed, begged, and bargained trying to get us to let her go to school!
I just don't understand. If my mom would have said you have to stay home even though you feel fine, I would have celebrated!!! But not my type A, first child. She did not want to miss school. Her sister on the other hand, she was just fine with it... she knows a good idea when she hears it!
