Confusing isn't it ALMummy.
You may remember my DS (4.5) has recently been DX with Aspergers.
He had no imaginitive play when he was say 3 and a half, only played with trains and cars and would copy sections of programmes over and over. He still goes over and over the same things, but has a wider range and will carry out a peppa pig dialogue using his disney pixar cars, for example.
A few days ago he said to me catch the ball mummy (always puts fear into me when we are in the house as he kicks high and hard). Imagine my surprise when he kicked a pretend ball towads me and I had to catch/head/kick it back (as I was instructed of course ).
He has also recently started to pretend that objects are other things, like Manny said about, i.e. a brick for a phone, but he then laughs like a drain so think he might be doing it because he knows it's the 'wrong' thing, don't know where this fits in.
He does lack social imagination, tho. He says that roads are dangerous, he might get bumped by a car, he has to hold hands to be safe, etc, but he still tries to run into the road if he gets angry/frustrated. He can't imagine what he has not experienced, I suppose.
