Chaz,my thanks for this thread. Very similar position to you and awaiting possible Dx of 2.3 yo DS who doesn't quite fit PDD or ASD or AS but is under investigation for them. 2.5 filmed session with educ. Psych. on Monday,filled in loads of questionnaires, seen developmental paed and now waiting for results and recommended interventions.
Thing is, DS just doesnt fit the triad of impairments for PDD/ ASD. H can cope with routine changes. He does do facial expressions and recognize them n ohers. He jokes, laughs, is silly for fun. Wide, not narrow range of interests, no stimming, good fine and gross motor skills, no sensory issues, eating issues, no health problems...but play is VERY self contained and can be highly focused for long stretches on whatever he is into, and he is socially absolutely not interested in other children and very shy with strangers. He is an only child.
It's all social problems. No natural smiling up, sharing and showing, no automatic collaborative reciprocal gaze, often chooses not to respond to name, ignores social overtures etc. But can be happily social with parents and trusted adults on his own terms. Treats play like fascinating work and gets annoyed if interrupted from concentrating. Cannot get enough of books. Wants to learn, learn, learn. Was terrible as a baby, wouldn't sleep, reflux, woke every two hours round the clock,screamed with frustration. Once he could communicate and run about he became so much happier. But he is not like his peers, won't play with his peers or even look at them or play near them, he stands out as the odd one out at playgroup, rhyme time, the park...he is off on one, not interested in anything other than what he is into.
Very very fast to learn anything he is interested in, astonishingly good memory for routes, stories - will fill in missing words of a story if i pause - without looking at book, after hearing it read only 2-3 times, and can still do so a week later. He can recognize words in a book and read them, can say numbers up to 50 if shown them, counts to ten and back again, counts up to six objects on a plate and can recognize if one or more removed and give new total, knows colours, shapes, various dinosaurs and all the trucks, started to talk in 2 word sentences at 2, now at 2.3 uses tenses, pronouns, plurals, dozens of verbs and adjectives, language is BOTH functional and echolalic - sometimes he seems very ASD, other times he is chattering on like a normal very verbal toddler, giving me a commentary on what he is doing, making conversation.
So I dunno. I just do not know. I mean, he's only 2. But all indications are early intervention can have huge benefits. He is meant to start pre school in September and at the moment I think he will HATE it. I need to help him cope. We manage fine with me devoting my waking hours to looking after him but how will he cope with the real world?
Sorry epic post.
