Proud Mommy Moment

My oldest son Gabe (4) is playing his VSmile, and all of a sudden, I realize he is getting up and going to the tv to count the little dots on the dice for him to play. He is doing math! I cannot believe it! I am so proud. Where did he learn this? I know I count sometimes with him, but he just did that on his own. All I can say is wow.
