Ben has been working on crawling for the last few weeks. He gets up on his knees and rocks back and forth. He has crawled like that a few moves at a time, but is also getting good at army crawling. Yesterday he became fascinated with crawling over to his exersaucer, scooting his torso halfway in to the saucer part, and repeatedly banging his toys on the saucer. Then he'd rescue the toy, crawl out, and then let the toy slide back in and repeat the whole process. Here he is heading for two of his favorite toys, the star stacker and giraffe block holder.
