My older son is 3.25 years old, and I recently had a routine conference with his preschool/daycare teacher. She said he was "not getting subtle social cues"; that he could recognize expressions like crying and smiling, but didn't get that someone standing with their arms crossed and head down, apart, could be sad or want space, and when people did something like that, he didn't "take the hint", and would still go up to them and bug them to play, etc. She also emphasized how "individual/odd" he is. I've read a ton on Asperger's now, and some things fit but a lot doesn't- I don't really know what to make of terms like "severe" or "marked impairment" in social skills, they seem vague and no examples given. I don't know if my son falls into that category. He has always made good eye contact, he likes other kids and wants to interact with them- although his assays are usually verbal and he can be awkward in groups--sometimes it seems like he doesn't see the way the group shifts to a different activity and gets mad if he feels left behind. He doesn't have a strict routine; like any 3 y.o. he wants some things a certain way but he doesn't freak out if they aren't; he has lots of interests and plays imaginatively by himself and with others--with variety in scenarios; he's very curious and interested in new things; he has some close friends and the teacher says he is well-liked by his class in general. He does also recite parts of books, movies or tv shows, sings songs with complex lyrics from memory, and wakes up in the morning asking when we can watch his favorite show.I feel like there are things he does that COULD all fall under the description of Asperger's, but he's not deadly consistent with them. Example: many mornings at school he runs around the playground a few times when he first gets there and then jumps in to play- but sometimes he just doesn't, or a friend will intercept him and he goes with it. Is that Stereotyped behavior? Is an evaluation warranted?
