My 20 month DS loves to name automobiles when out and about - and loves to look at his flash cards and name them, or his wall mural. And he loves the flat puzzle with cars, pointing them out and pushing them into place.
But he rarely picks one up and plays with it, or pushes it along the ground. He'll get in his little car or push that along, but none of the small ones. if we go to a playgroup and he sees one there, he'll get down and push it for a couple of seconds but his attention won't be held for longer than that.
I find it quite unusual since most of the others his age are always holding or playing cars or interested in the wheels.
It's not even that he has any other huge interests - he just moves from one thing to another very quickly.
Is this unusual and/or age appropriate? And that he likes naming them but not necessarily playing with them?
