Hurrah! The experts and I are in total agreement as to what my ds1's issues are and what his strengths are. And they do want to give him a diagnosis of aspergers syndrome. Now school, parents, paediatrician and psychologist are in total agreement, I guess it's a question of fighting for a statement. I wonder how many years that will take...
Ds1's main issue is with empathy - he understands facial expressions, eg that people are angry or sad, very well, but he just doesn't have a very good understanding of why they feel the way they do... Fantastic imagination, though! I'm sure we can take advantage of that to help him learn why people might react the way they do to him and others around him.
Thank you to everyone who supported me in my wobbles on the way to the appointment!
