Ok. So. Update.
No going back to neuropsych. It is not approved by insurance. He got to go there to get his diagnosis (aspergers) when he was 3, and got seen once again at 4.5 years old, at which point he was doing so well, she said she didn't need to do more follow up. We cannot take him back.

Gosh. Apparently when we got that dx at 3yo, we weren't aware that was it. Done. Period. At that appointment they didn't even do any actual evaluations, just observed him informally and asked us questions.
