DS's school have said they think he has ASD so I've been doing some reading and also booked an appointment with the GP. From some of the questionnaires I've looked at, he certainly ticks some boxes and has obvious difficulties with some things, such as social and personal boundaries (hugs people a lot, likes touching people, joins in with the conversations of random people on the street, but also gets very upset/aggressive if someone invades his personal space), but also doesn't tick others.
I was reading an extract from a Tony Attwood book from a recommendation on here and it said something along the lines of AS children being unable to read facial expressions, or make expressions themselves on demand. It didn't say 'some AS children', it was simply a statement and it said that other children would find this easy. So I 'tested' DS, asking him to read my expression while I pretended to be happy, sad, angry, frightened, confused, disgusted and he could do them all (although tbf I did exaggerate them). The next day I asked him to pretend to feel the same expressions and he did, fine, no problems. He's not quite 5 so it's not hard-won learned behaviour, if you see what I mean.
So is this something that an ASD child should definitely struggle with and is school barking up the wrong tree? Do I need to be looking for something more subtle? If I'm going to talk to the GP I want to be confident in my facts.
