Do you fight this battle?

So, I have a 5 year old with definite opinions on just about everything...she's been that way since the day she was born!  But, at our house, "mommy always wins" and there are rules that help us all keep our sanity.  

As we begin the kindergarten year, our newest battle seems to be clothes (actually we've been fighting that battle since 3 year old pre-k) it comes down to "you can't wear a dress/skirt every day and you're going to have to wear PE shoes. "

As a teacher, I have a hard enough time remembering which special I have which day, let alone keeping track of her schedule too, so we made a note and taped it near her closet that says which days and states no skirts no dresses, voilà, now there will be no argument since she will at least comply with written rules....I wonder how much longer that will work?  Hee hee!  Oh, well!
