Crawl!?!? ...Why crawl when I can roll?

So... Olivia rolls and rolls all over the floor, from one end to the other... and she gets there pretty quick (when she's determined). As long as her body is positioned so that the object is at either side of her she rolls and rolls. If not, she has figured out that if she turns her body to the left or right, then she can roll and get what she is after. As for crawling, she can work her hands, but her knees are not quite coordinating with the rest of her body yet. Now, since she couldn't figure out her knees, today she got on her hands and feet, with legs straight, and into an arched position. In this position she is attempting to get somewhere, which usually ends in a face plant. She still can't figure out how to work it all, but she's definately trying... Its hilariously entertaining to watch her little mind at work, looking down at her feet and hands (as she is about to make another face plant) trying to figure out why they aren't cooperating together.
