Jacob thought it was so much fun to sit on his chair alone and discovered that it moved when he hopped. You can imagine what happened next, as seen in the progression below. By the third picture, I was convinced he was going to fall off, but alas, he did not.
Below is the one and only picture I took of Jacob in his 12 month onesie. Although I'd prefer to have his thumb out of his mouth for the photo, it was the only shot I got before he continually rolled over and crawled away. Argh.



Finally sitting still!!
