Do you find you have to explain everything at least twice to them?
I mean simple things in everyday conversation like,
"We'll stop for lunch soon and get some sandwiches",
becomes "We'll stop for lunch soon and get some sandwiches. Because it's 1pm which is lunch time. Are you hungry? (Yes) Well we'll get some lunch then. Would you like something else for lunch? (no, I like tuna sandwiches) Well, shall we get some then? Because it's lunch time. It's 1pm. 1pm is when people eat lunch. Yes, you can have a tuna sandwich. I know you're hungry, shall we get some lunch? EAT THIS TUNA SANDWICH!!!!!!!
I have been told dd is pretty bright and only mildly ASD, but sometimes she seems to not get the simplest of concepts. Perhaps what I wrote above is not the best example, but just having a conversation in the car as a family is impossible because everything has to explained so many times, and justified to the nth degree.
(have just had a 5 hour car trip and am exhausted in more ways than one!!!)
