DS will be 4 at the end of the year. I've noticed that his pretend play doesn't appear to be as well developed as some of his peers - this is mainly just from what I've seen in parks etc, but also compared with one or two friends' children.
He has no problems playing pretend of basic, every day scenarios eg will make pretend food in his kitchen, pretend to go to the shop, pretend to give his baby doll milk or take it for a walk in its pushchair (he has a baby sibling). He also pretends objects are something else (he does this well/a lot). He'll wiggle on the floor and say I'm a snake! Or occasionally say there's a monster or something.
But that's as far as it goes. The peer children I've seen seem to play pretend much more elaborately eg make a huge game of it. DS' pretend play is always short lived.
The main thing he does when playing - and I mean up to 80-90% of the time - is drive vehicles around or pretend he is on a vehicle (eg ship at the park) and make the relevant sound effects. Over and over again. There is the odd bit of standard narration eg "land ahoy" if he's on a pretend boat, but it's mainly the sound effects.
Is this typical? I don't think it is, but I don't want to seem fussy...
What are your 3-4 year olds' pretend play like?
