Say Yi1

I often play this game of holding out fingers and saying each number from one to four (in Chinese). As I held out my index finger and said Yi1 slowly, for the first time, he slowly extended out his right index finger from the little fist just now. We repeated the game a few more times reliably. It 's such an exciting moment for me. I tried to capture it on camera: pictures here.

We tried other numbers, he attempted to open more fingers but the hand coordination wasn't there yet.
