Hiya. DS1 has AS, he is 5.
Sam pretty much displays the behaviours you describe, although he is good with both adults and smller kids- just not peer group. He also is extremely routine orientated (for example, taking him to a different supermarket will result in him crawling or shrieking around for the whole trip), is obsessive over certain things (Dr Who, for example), cannot share or identify with others at all and displays extreme reactions to emotional triggers... either completely oblivious (usually) or terribly distraught (eg if a baby dies in a TV drama).
He is also very particular about soft clothes, food smells and not good at touching / eye contact except with me.
He also suffers sleep disorders and is very confused about things like morlas (he steals unfortuantely), and can't always tell fact from fiction.
The National Autistic Society ahve a good website and a helpline that is worth talking to, they have exceptionally good factsheets.
NAS
Because of the trouble you've had getting a diagnosis, these poeple may well help... we're going Monday but they don't suit everyone.
