letters and numbers update

We have been playing more games with Sam that have numbers and letters in them. I especially try to get him to play cards with me. Whenever we play cards he knows all of his numbers. And we are learning about J, K, and Q jajaja. Grandpa also asks him lots of number and letter questions. The other day he knew all of the letters in Omaha. Hello! I didn't think he could do it. He obviously knows more than any of us give him credit for.
