Indigo thanks.

As for the legal side, we have a lawyer retained from the top special education legal firm in NYC. She has been very skilled in guiding us.

The understood website advertises heavily in NYC and I've checked it out. Some nice resources and articles. You can tell dedicated non-profits are behind the site -- they focus on the right spectrum issues (e.g. how parenting an SN child impacts marriage).

Thank you for the recs.
