DS (who is DC3) is 2.5 plays with 1 thing and 1 thing only - cars
He has a toy garage, but it's rarely used. He is simply v v content to drive his many, many cars around the floor and furniture
It's gorge to watch but I wonder if I should try and get him into other stuff . He very occasionally does other things but it's short lived
My DDs weren't like this IIRC. Funny how different they can be
