It's really amazing to me because he went from not recognizing letters at all to asking for reading lessons at school.
He reads "Dot" as DUH-AW-TUH. Then he says it more quickly. The he says DOT!
The words are small, mostly three letters. He was pronouncing HAS as HOZ, but I think that's because the letter "a" looked like the letter "o" to him. It really did, too.
I know it's mundane because it happens everyday. But, it's amazing because it's happening now!
