Isaac's sitting skillz

You may have noticed (below) that my darling baby has become a near-professional at sitting unassisted. I just noticed this today. We hadn't been practicing sitting so much as crawling, so today I figured we should try to give it a shot. I would help Isaac assume the traditional yoga-baby-bent-in-half pose that we used to call "sitting", and then he would promptly use his massive tummy and back muscles to lift his torso so that he could sit STRAIGHT UP. This kid is going straight to the Olympics, I tell ya.
