My 3 year old DS is obsessed with numbers. Obsessed. He talks about them constantly, and has done for over a year. Everything else we do ends up about numbers, e.g. playdoh, swinging at the park. In the car he just reels off numbers for looooooong chunks of time. Odd number, even numbers, all the times tables, up in 5s or 10s or 3s or 50s. He runs around shouting numbers when he's playing. At the water park he didn't splash in the water, he just bent down and traced sums in the puddles. He can do addition and subtraction.
It is endless and it's driving DH and me absolutely up the wall. I'm starting to feel like it's just not normal (I know that's not the best word to use). He's an anxious little boy as well, but not overly so.
Anyone have any experience of anything like this?
