Spook, it sounds like you have one like mine! DS who will be 7 on Sunday, when he was 2 and 3 years old, knew everybody's license plate number, phone numbers, and ran around counting everything and nothing in particular constantly.
I remember one time when he was 2 1/2, I had told him when his birthday was, and then a couple weeks later he told me in the morning that he wanted ice cream. I said "you don't get ice cream for breakfast, silly boy, the only time you might get ice cream for breakfast is on your birthday!" And he looked at me, and I could see the wheels turning, and he said "Ice cream...birthday...September 6th!" Funny thing is, I remember thinking at the time "finally--he knows it now!" because it seemed to me that it took him a long time to learn that, for a kid who knew every number in the neighborhood.
