Interest in crawling forward?

The cold is still hanging around but Thomas appears to be feeling better and is on the move. He's enjoying tummy time (finally!) and almost seems to prefer it so he's been hanging out on his belly quite a bit. He pushes himself around in a 360 degree circle and pushes himself backward, but hasn't gone forward yet. He like to rock forward when sitting and enjoys throwing himself forward, esp. when we are holding him. I still think he may just start walking before crawling, but only time will tell.
