Babs still isn't crawling. And that's okay with me. What she is doing is getting very close.
I used to be able to leave her sitting down, and when I came back four or five minutes later, she'd be just where I left her. Now she's learned to lean over onto all fours, think about crawling, even lifting one limb, then reaching out in the direction she wants to go, and falling to her belly. She then reaches whatever it is she wants to get. Or doesn't reach it, and flails around trying to get it.
What this does mean is that the radius of safety that I have to keep around her keeps getting larger. Which really means that the things that I've decided are okay for her to have keeps growing.
