Kate explains it well here. But what she didn't tell you is that she ran, jumped on trampolines, skipped, hopped, slid, danced, and climbed trees on her broken foot for a week before her dopey parents got her in to a doctor. But to our credit, it didn't really swell until 4 days after the injury and she never uttered one word of complaint unless we asked. She slept through most of the casting process and it still doesn't slow her down one iota. We went to the mc donalds playland today and she played tag with the other kids with no problem. I think she might be the type to have 5 kids with no epidural and come out smiling at the end. She sure is cute with that little cast on!
