we have 2 of these - ds 3 is deep in dino territory (we love dino dan). I had an argument yesterday with him about whether his new car seat should be sand or beige.

Once when dd was 3 her granny asked her to count all the cars on the street. DD replied there are 4 cars granny, who said no there are 7, oh said DD you mean vehicles right then there are 7 vehicles, they are 4 cars, 1 ute and 2 trucks.....

I don't think it ever goes away.
