Wilf, I've just briefly scanned these 2 threads and wanted to share some of my own experience with you.
DS2 has Asperger's traits but never merited a full diagnosis. He's one of twins and was so different from DS1 from infancy that I knew something was not quite right. I was both terrified to have a diagnosis and yet seeking some kind of explanation.
At 2.75 he was assessed as developmentally subnormal byt an academcially selecrive pre-prep school, whilst they loved his twin and offered him a place. Around age 5 to 6 he had speech therapy and the therapist told me that he clearly had special needs and would never get into any of the local fee-paying schools (which had been my hope for my twins).
I used to come away from appointmens in tears, as the label, 'Special Needs' was like a knife in the guts. In my family of origin, being anything other than at least super-normal wasn't acceptable so to feel I had a son who was sub-normal, atypical etc etc (and I use those terms deliberately here to indicate the emotional power they had on me), was a complete devastation to me.
The twins are now 9. DS2 is racing ahead academcially in the most academically selective school locally. My 'developmentally subnormal, special needs' child is thricing way ahead of his more neurotypical twin, who is actually now struggling and may show signs of attention issues, processing difficulties etc etc.
What's helped along the way is realisng that i actually know few is any other children who are problem/ issue free and who haven't got some kind of quirk or challenge. The school my twins attend is packed with really eccentric children who might be supergenius in one area but struggle in others - especially socially. DS2 fits in here v well so far, although i realise that he'll have more difficulties as he gets older/ reaches adolescence.
Along the way, many people got it wrong - but also got it right too, in so far as he clearly isn't an 'average' child and clearly has certain quirks.
But what's helped me most of all to diffuse the knife in the guts feeling has been retrospectively to consider myself and my own family of origin. I can see how all three of my sibs and I could have merited diffreent kind of diagnoses were we assessed today - Asperger's traits/ ADHD etc etc - AND our parents and their parents too. we're a really weird family - but then if I look around, I only know a handful of people who aren't really weird too, in some way.
So by realisng that perhaps I could be deemed to have x/y/z and yet here I am, still thriving in life, then DS2 (and DS1) have every chance of learning to live with their eccentricities and particular challenges and I'm a good example of someone who has survived and thrived, with all my eccentricities and idiosyncracies.
Somewhere down the line, when the dust has settled, I'm sure that things will be easier for you and you'll have found a way of accepting we are as we are and either you can stick a modern label on this (because sometimes this helps) or you can simply focus in on the collection of qualities that makes you and your DC who you are, without putting this in a 'box' or category.
I still don't really know if DS2 could be deemed to have SN (I personally hate that label) or just some quirks that make him uniquely who he is. There was one recent situation when it was very helpful for me to inform someone that DS2 had Asperger's traits but another and different situation where I was outraged that soemone declared to me, "Is it Asperger's?"...
like, NO IT isn't Asperger's - HE is my son and in this context, there's nothing helpful about using that term!
Good luck
