Two of my favorite bloggers have written similar posts both inspired by an annoying Age of Autism rant (that I won't link to for the same reason that Emily didn't). Also, their reactions are great!
Emily's post on Anger Management exemplifies good parenting and a good attitude and everyone should read it.
Hammie's discourse about Shiny Happy Mummies does the same thing and has a link to a student who wants to study the positive perceptions of parents of children with autism.
The two bloggers above are among my role-models. They tell it like it is, the good and the bad and you know what? It's mostly good.
