Crawling or Gymnastics?

Last night while Daddy & Grandpa Jim were watching (trying to watch) the OU game Grace started practicing crawling....or at least that's what we think she was doing. She was on her belly then she'd pull her knees to her chest and lift her upper body up with her arms (it sounds like she's trying to crawl, right?) well I guess she would have looked like she was crawling if it hadn't been for her head being down on the ground like she was about to do a somersault. Yep, she holds her upper body up with her arms and the top of her head.....I think Madeline taught her that!
