I only have the one DC (DS, will be 5 next week) and I feel like he's quite different to other kids his age. Wanted to gauge some opinions. For the most part he's a lovely, gentle little boy, very affectionate. He started school in September, enjoys it, seems very bright, teachers have no concerns. However I sometimes worry that he has a lack of imagination. He absolutely loves to draw and do craft and so on but he will ask me to find a picture of a craft online and will then want to copy that exactly - if I make any suggestions to do anything differently, he won't want to. He will draw but he will quite frequently (not always) draw the exact same thing. He loves to play with playdough but will play with it in a very specific way - e.g. he has a cupcake playdough set and if you're playing it with him you have to do it in the exact way he says or he gets annoyed.
I once spoke to a child psychologist friend of mine who said the key flag for ASD re: imaginary play was more that ASD children cannot pretend things are other things - e.g. if you give them a spoon and ask them to pretend it's a person, they won't be able to do that. He definitely can do that and frequently pretends objects are other things - it's just that he will play the game the same way every time. He has cuddly toys but he doesn't name them - if I ask them what their name is he quite often says the same thing for all of them (e.g. "Rainbow"). When I was little I used to play loads of mad imaginary games (on my own or with my mum, I am also an only child) where I made up all sorts of characters and scenarios, and he doesn't seem to do that at all. Other children his age seem to do this.
Another thing I worry about is that when he is crying he finds it very difficult to calm down. So I implemented this thing where we would do a "calm down" count - e.g. I would say let's take a deep breath, count to ten and calm down and then I would count (not in a time out/punishment sort of way iyswim). That worked quite well but now if he cries he says he can't stop unless I count to ten.
This is really long and rambling but I just feel he is very literal and very anal and I worry it isn't quite normal for his age. Has anyone had a similar experience with their child?
