He's almost got it. He gets up on all fours and rocks but he hasn't quit figured out yet how to move those arms and crawl. He can even sit up from a laying position, although I haven't seen him do it yet. I've left him lying on the floor and next thing I know he's sitting up...I keep missing it. I'm sure that within the next couple of weeks he'll have it down and be crawling all over the place.
