Thank you , LeonieDelt and Handywomen. It feels strange to actually hear that my feeling may be right. I am not sure about the other parts of the triad. I have always thought of his behaviours as "just his personality" so is difficult to know what might be ASD behaviour.
I am starting a diary. Yesterday, when we were in a very busy shopping centre and cafe, I noticed he could not cope with this. Before yesterday I would just have got on with it thinking he was being a bit difficult but now I am wondering if busy places are a problem.
He is only interested in doing the things he is interested in. Will not sit still for a minute, listen, discuss, play if it is something he is not interested in. Is obsessive about his interests.
Very clingy to me, can be stange with others eg asking them not to speak to him, not to touch him. It is a bit upsetting for my mum when he is like that (which is almost all the time at the moment).
Problems eating certain textures, limited diet, wants same meals at home. Always has to have what he had the last time he was in a restaurant, cant cope if he cant have it. He has a tongue tie, so unsure if this has caused the eating and slight speech issues.
He does something strange with his hands but never thought of it as hand flapping. It is very intense, I think it is when he is in is own world replaying something he has seen on tv in his head. Or he is pretending to do something.
Are any of these things on other parts of the triad? LeonieDelt, do your children go to school, if so do they need extra support?
