The teacher inside me knows he will be fine. It is like parents who have kiddos that are 4 and aren't potty trained yet. They will be fine. They will get it. I know Johnsie will get it.
So, here's what we did for a few minutes today anyway. Because of course his attention doesn't last long.I got 3 cups and some letters and put a letter under each cup.
I would mix them around and Johnsie would pick one and then he had to tell me the letter. If he got it right he was given a jelly bean.
After awhile he decided to put 2 letters under each cup. This of was not because he wanted to learn his letters but, that he wanted more candy. I guess we probably did this for about 10 mins so he I guess he actually lasted pretty long.
