Thomas and the stairs
Honestly, I don’t know how we’ve gone on so long without Thomas even attempting to climb the stairs. He just hasn’t seemed to notice them, until this weekend and now he think’s they’re awesome. 
The kids all think it’s great fun to see him go up the stairs:
He does like to stop crawling up and stand up, which can be a little disconcerting, but luckily our stairs are broken up by landings so he can really only fall down 3 or 4 steps at a time, if he does fall.
So far he has only learned how to go up. The kids and I have been trying to teach him how to go down by showing him that he can go backwards on his tummy, but he has yet to attempt a decent down the stairs.
