Kai is trying to sit on his own

Yesterday Kai was in his bouncy seat and pulled himself up into the sitting position. He wants to sit on his own badly. Most of the time he tries and can't do it, but yesterday was a big moment so we captured some pictures. The bottle was in front of him (you can't see that in the picture), and he was just staring at it when he wasn't looking at me. I think he was proud of himself.
