Push-ups and pulling up

Aden is already pushing himself up and pulling himself up on things.  Last night after giving both boys a bath, I put Aden on the floor while drying Rainey off on his changing table.  Aden crawled (yes, he is crawling and has been for about a week) back into the bathroom and pulled himself up on the side of the tub.  I walked in the bathroom to him standing up on the side of the tub.
