moving towards crawling

Cole is going to start crawling any day now, I just know it! He is making strides towards it every day. Just this weekend he started doing this pilates-type move where he gets his butt way up in the air. You can see in this series of photos how he gets his knees underneath him, and then gets himself up there. The next thing he does, usually, is he ends up rolling over to the side. Today he started being able to get himself from a sitting position to being on his hands and knees. It's fascinating to watch him learn how this is all suppose to work. And I find it just amazing that babies just know what they need to do to become mobile. I know he's going to love it when he can move. But I'm not sure if we are quite ready for it! Can you say babyproofing? Um, yes. We need to get on that soon.
