Standing and stair climbing

Earlier this week - poor 2nd kid, I don't know the day anymore - I looked over and Corin was scaling the stairs. He had it down. At this point he has the stamina to cover the bottom half. I need to figure out how to gate spindled stairs.

He's also proved to me in the last day or two that he's capable of standing on his own for 5+ seconds at a time. It's getting longer and longer and he's doing it more and more. He still isn't ready to make the leap to steps across a void, though; he'll fall to the ground and crawl. His falling is very controlled.

Physical milestones abound. Some talking, too, but more on that later.
