Like I mentioned before, James shows much more interest in moving himself around (scooting, rolling, etc.) than in learning to sit up. This weekend he made some huge progress in learning how to crawl. He alternates his hands and feet just like crawling now, and he can push himself up onto all fours. I've been trying to get a video of it, but like most babies do, he freezes pretty much as soon as he sees me with the camera. I'm going to keep trying to catch it, but until then here's a cute video of James moving around a bit.
