Natalie still shows no interest in crawling. But she's getting good at scooting around on her bottom from a sitting position. Nowadays, we can set her in one spot, and the next time we look up, she has moved a couple of feet.
But she is also scooting into some inconvenient spots, like under one of our Swiss chairs. This has happened a few times and we've had to come rescue her from the snatching chair.
