He holds himself standing up on a toy, moves to another toy (still standing) and back and forth. he put his leg up on the side of one toy, like he was going to climb it even though he's just getting the hang of holding himself up. Then he falls , bomps his head on the carpet, looks up at me and grins, and then turns around, crawls to another toy, pulls himself up to a standing position and starts all over again. Ah, the world is such an adventure.
