Right, a moment's peace, finally.
Thanks everyone, it all looks really helpful.
as for questions asked:
dx paragraph states: 'these difficulties confirm she fulfils the diagnosis of ASD (DSMV). Given her early language skills and articulate presentation, parents should access information under Asperger's syndrome' which neatly bridges the getting-rid-of-AS-as-a-dx bit. So technically she has the same dx as dd1, which one day she will read herself (in all probability), and I don't want to lie to her about that. Am happy to stress the AS part, though, as she is clearly very different from dd1 (on the surface at least; in actual fact, they are the very definition of language skills splitting As from classic autism! dd2 has all the same issues, mostly to the same extent, but given her language skills, and coping mechanisms which arise form being a girl, she can rationalise a lot more and so can cope so much better. dh and I have often joked that the difference between them is that dd2 doesn't have the severe language disorder).
I have been recommended All Cats Have Asperger's before. I am resisting buying it because I dislike the implication the title seems to have - that 'we are all on the spectrum' angle. I don't think we all are, and I'm not sure it would help dd2 (I realise I am overthinking, as it would appear to be about cats
, but let's face it, she's not the greatest at generalising and learning form inference
). I would be happy to be told my thinking is bollocks.
I will watch the video in a moment, zzzzz, 
dd2 is 7, jellyhead. dd1 is 9 (and ds, who is also in the system, and who dd2 keeps saying 'I hope ds isn't autistic, like me' about
is nearly 2).
lougle - I don't know any cool people in RL with AS (aside from probably me, and my brother. not sure we'd count as cool to anyone though
). I am wary of the 'famous and cool' aspect - eg Bill Gates/wildly successful types, as she is such a perfectionist already, and then to fall short would be damaging, I think. I don't need her measuring herself against hugely successful people at the moment - she seriously has no concept of adult/child differences, and so would literally measure against successful adults, and feel a failure if she cannot instantly do the same.
thanks for the book references - I like the sound of mini-novels, and anything with 'different is good' is a good start in our house. zzzzz - the Wrinkle Quintet has a reading age of 10+ on Amazon US. Is this accurate, do you think? dd2 has a technically advanced reading age, but severe processing problems leave her general understanding of the story/plot at around the 10th centile, so quite severely behind.
to everyone, this has been really helpful.
