Practice standing

Henry is getting much bolder about letting go of the things he's using to steady himself. Several times a day I'll notice that he's let go of me and standing unassisted, at least for a couple of seconds before he slowly bends his knees and sits down.

He seems to especially like standing on the mattress next to our bed - he'll let go of the bed, bounce his knees once or twice, and then quickly fall / sit right down.
