How do I do this now?

Maddy is learning how to get around. She commando crawls most of the time. But tonight, she tried something different. My mom was watching her and said she got up on her knees and "walked" forward about four steps before going to her hands again. Odd. Just odd. I don't doubt it though. Right after that, she did a bear crawl and a real crawls in a matter of moments. I thinks she's trying to figure it all out. Cute.
