A series of Lydia showing how well she sits up, and how she's working hard towards learning to crawl. She scoots backwards pretty well, and rolls like a champ, but is still working on forward motion. Oh, and one of the pictures has a pretty good shot of her 2 lower teeth. On a related note, Colin lost another tooth a couple nights ago and has 3 more loose. I think it's going to be a gap-toothed Christmas around here!
