The boy - he crawls?

No... it's more like a slither, and only in the backwards direction. This doesn't so much suit his purposes, however he is enjoying finding new toys as he moves backwards, they're like suprises! So now he can turn 360 degrees and move backwards ... he's sort of like the lady who's afraid to make left hand turns, he can still get anywhere, it just takes him longer to figure it all out.
