Kurly, just read a question you asked in one of my thread about my ds's asd traits.
I'll try answer here as briefly as i can but the list is long.
My DS is biggest isssue is with speech and lang. (he is p/t in a sen lang. unit), but he has other issues which affect him more mildy than his lang. problems.
He has diffculties socialising with peers, joining in games at nursery in an age appropriate manner. I mean he is not a total recluse, (although he used to be when he was 2 and started at nursery), but his approach is awkward, he doesn't always understand what they say, how to play, he struggles with sharing, waiting for his turn, he copies his peers, totally mimicry what they are doing as a mean of interaction,...
He has sensory issues with some textures, foods, hates gooey things, getting his hands dirty, doesn't like sudden noises (he covers his ears), he is sensitive to some lights and goes into overdrive in supermarkets and shops. And he has some stims as i mentioned in my other post.
He has some delays with his imaginative play, quite repetitive, likes cars and trains, limited pretend play, never drawn a pic that ressemble anything, never named a toy, quite a concrete way of playing.
His has some rituals he likes to do in a specific way in some situations, especially during transitions like leaving the house, getting in and out of the car,...
Hope this list helps, but bear in mind that asd is a wide spectrum and all children are different.
