DS is 2.8 and doesn't really do much imitative play, if at all.
He knows what things are for, ie hair brushes, phones etc (he has had a pretend telephone "conversation"), but he doesn't really push cars/trains around and that kind of thing. He never puts on my shoes or similar like my niece and nephew did with their mum.
He likes looking at books, and sometimes he recites bits he remembers. He likes looking at my books for the page numbers as he loves numbers and letters (he can count to 30 and knows the alphabet) and he likes to line his peppa pig magnets up and say who they are. Very rarely they will have a small conversation with each other within the limits of DS's vocab.
Mostly he likes naming things - circles, squares, characters - and putting different things in different groups, or different groups of things in different places.
DS didn't start speaking till late he was about 2.2 months, so it may be related to his ability to express himself, but I am quite worried about his lack of imitative play.
How does your two and a half year old play?
