Jack is thisclose to crawling. He gets up on his hands & knees now, and will rock back and forth before collapsing back down into the carpet. He uses a combination of scooches (generally backwards) and rolls (usually to the left) to get around for the time being. I think it's only a matter of time before he will be on the go. I'd better finish up the baby-proofing!
Could he look any more like his Daddy? Jack is quickly becoming a mini-me :)
