Count to 10

I heard Michael count to 10 by himself for the first time.  He was with Grandma in the backyard and put his face in front of my bedroom window when I was sitting in bed playing with the iPad.

He counted to 10 in perfect Mandarin. Mentioned it to my wife and she said "yeah, I've been speaking to him a lot in Mandarin."

I haven't heard him count to 10 all the way in English or Cantonese yet.
