Is this the determined face of a soon-to-be crawler!?!

We thought it would be a while before James started to crawl but this week he has been lunging forward from the sitting yoga/frog position more and more and holding himself up for longer. He's not covering any ground yet (apart from the initial lunge!) but we're starting to wonder if maybe he will be moving by the time we come home. Maybe there's a big step between this and actually moving and we know he'll do it in his own time but it's quite amazing to see how strong he's getting.
