The Bean is getting up on all fours now. It's very exciting. In just two short weeks, Bean has gone from dragging her little body across the floor using primarily her arms, to using both her arms and her knees to wriggle, belly down, across the floor, and now she's getting up on all fours.
She doesn't quite know what to do once she's up there, but she's clearly quite pleased with herself. She gets up on her hands and knees and rocks back and forth and back and forth. A couple of times she's actually picked up a hand and moved it forward, but it usually ends with her knees slipping out from under her and her belly back on the ground. But she's all smiles and just keeps getting right back up again.
As soon as she figures out the crawling on all fours thing, I think the cats are going to be in for some real trouble.
