Mal, what are the chances of an expert in early childhood 2e "just happening" to be already a trusted adviser, AND willing to take a quick look at your DS! I'm very happy for you and your DS. It's hard enough not to doubt oneself as a parent to any child, let alone a low-incidence child...good to have an IRL expert to give you perspective.
