Hi, most parents may have seen this but just in case it helps here's a link to a new publication:-
www.ambitiousaboutautism.org.uk/page/who_we_are/news/article/index.cfm?articleId=33
I really hope that this does have an impact on the professional/parent relationship for lots of parents, the same issues arise in working together for those of us with children with differing disabilities, hope this is useful :)
