what should a fifteen month old boy be expected to show in the way of pretend play? I don't really understand this. He has a few words but mostly likes to explore and throw balls and build. I will take his teddy and we'll do teddy's teeth or we'll feed him with a spoon and he gets it and copies it but I always initiate it. Is he expected to do all these sorts of things at this age? Or should I be worried that he isn't pretend playing enough? is there things to do to encourage it or is he too young
