What a GREAT picture. What a cutie.
As a teacher, I was ready to hear this incredible story. I have had the chance to hear a 2 year old and 9 months read a book. The interesting thing was that he was reading new words that he was not taught, like "stationwagon". Teaching a child to memorise is one thing, but reading at a young age is simply breathtaking.
Keep offering him reading material on the pottie and I am sure soon enough he'll be reading.
