My son had an evaluation at Yale Child Study when he was 3 yrs old. They were wonderful and did a very thorough job and sent us on our way with a very detailed report.
I would have taken him back, but our current insurance doesn't cover Yale Child Study...and then we ended ended up in the psychiatric hospital...yadda, yadda, yadda.
As of right now, our next "evaluation" will be a neuropsychologist. Have you pursued a neuropsychologist yet?
