Is this response typical from what could be an ASD child?

[Pinkchampagne]

I say "could be" because we haven't got a dx for DS yet, but is being tested for ASD.

It was DS2's birthday party & I said DS1 could have a friend round too. He chose a friend from his class that he likes to play pokemon with & this friend came round to the party, but a few minutes later another boy from his class turned up with his younger sister & I felt I should invite him to stay too, as the family are new to the area & I thought it would be nice for DS1 to have another friend his own age (I know he likes this boy as he has mentioned him to me)
I wasn't prepared for DS1's reaction. He ran off crying into the toilet because he only wanted the friend he was expecting round and couldn't handle them playing another game on the DS as he only wanted to play pokemon. I just couldn't reason with him at all & was quite shocked at his response to another child in his class being invited to join them. Eventually (when they agreed to play pokemon) he came round, but it was hard going & his behaviour seemed selfish.
Does this sound typical AS type behaviour?
I am finding DS hard to deal with at times as I don't understand him.

could be or could be nt child strop too. can't really tell anything from one incident, only by building up a pattern of behaviour.

so if this one time, he had a tantrum because someone showed up that he didn't want to play with, then could be asd, bratishness, bog standard kid, bad day, whatever..

if it is the latest in a long list of occasions when he has flow off the handle if things do not follow the expected path, then more of a case for arguing asd, imo. iyswim.

Sounds like typical asd behaviour in the your ds had a set thing planned in his mind and when it was disturbed/changed he couldn't deal with it. Very like my dd with AS!

There are lots of other things that raise alarm bells for ASD - I guess I just wanted to know if this was typical behaviour from an ASD child as I found myself getting quite cross because he was appearing selfish.

yup. asd = appearing selfish disorder it can be very hard for them to see things from the other pov, being focused on their needs tends to be the thing, I've found. - although they can be sweet and kind and thoughtful, I'm not saying they ARE selfish! Mine have been wonderful since I got out of hospital, very thoughtful.

My youngest is worse for this than my eldest, he finds it almost impossible to consider others spontaniously, iyswim.
