he's a climber!

We're going to have to anchor our bookshelf to the wall. Mason is attempting to climb it. We have the two bottom shelves for toys, and the top three for books. He's been putting his feel on the bottom shelf and trying to lift himself up.
He also climbs on the tupperware bin we have for his toys. Ahh, and it's just going to get worse, he hasn't even begun to walk yet! His balance is getting so much better now too; he can stand for a while without any support.
