The cool thing? I've been trying to teach him how to scoot down the stairs on his butt (since he was opposed to climbing down backwards) and he's figuring out how to walk down on his own. To me, that means he's problem solving.
The other thing it shows is just how opposed he is to using his hands. Most kids would learn how to walk down the stairs by holding onto a railing. Elijah has never held onto anything while going down the stairs other than our hands (which he's done a lot, so he's had lots of practice). It would be so much easier for him (and safer!) if he'd just hold onto something. I have to say, though, I love this kid's determination.
