Look at this kid, will ya? Not even 4 months old yet, can't sit up on his own, has not completely got the rolling over thing down, but he can stand up for a little bit at a time basically unsupported. My hands are there just to help him stay balanced and to provide some support when his legs finally get tired & he's ready to sit back down. He thinks this standing business is hugely entertaining, absolutely loves it. It's really quite something.
