I really like sitting in this chair Mommy! I'm sorry I spit up on my shirt when you went to get your camera to take a picture of me looking so handsome. Just for you, I'm going to try sitting up on my own. It won't be easy, but I it's worth a try.
I think I'm doing it, but are you sure this is safe?
Please don't let me fall, please don't let me fall....
Now this is more like it!
(Please be sure to keep your attention focused on the smiley little boy and not on his old looking mother who really needs to avoid close up face shots, put on some make-up and do something with that hair.)
