Why this is just the cutest picture ever to me...
Look how worn out his little slippers are already...like he's been walking miles.
And his big old blue bottom...love it!
And mostly because his head is down.
This is the serious, tuck in the chin, look at the floor, concentrate on the arms, and get there fast crawl.
Cracks me up.
Sometimes it backfires and he goes head over heels. Or heels over head I should say. But he's mastered it pretty well.
He usually only uses it to get to something really good, meaning -dangerous-...stairs, Lego pieces, fallen food scraps, doors open to outside...you get the picture.
