These are a few weeks old, but Timmy's started to move quite a bit! At this point, he can move from one side of a room to the other, and even made it to the doorway of Jeremiah's room (I'd put him on the rug). He's not crawling yet, but he's scooting. He sticks up his rear, puts his head down, and pulls forward with his arms. And he rolls all over the place. We don't have much space, so he usually tries to eat things he shouldn't (strap on Jer's booster seat, curtains, leaves, dog, etc.).
