Bitty's cognitive and verbal skills have just expanded by leaps and bounds this year! The concepts that he focuses on crack us up. A while back, he figured out that whenever he asked for something and I told him that we were out, the next step was "You go store? Buy some?" Now he has begun applying that to things he wants, as well.

Me: "Let's put your shoes on so we can go."
Bit: "Wan' wear fwog shoes."
Me: "You don't have any frog shoes."
Bit (thoughtfully): "Hmm...wan'...you wan' buy some?"
