Standing

Not necessarily for an extended period of time, and if there is any kind of breeze at all, like a fan, or a sneeze, he may topple over, but he is definitely standing on his own.

So far it is mostly just delayed falling, but he has the concept, and if you hold his hands he'll truck all over the place.
