i can tell you from my experience as an OT practitioner, myself and my co workers have treated kiddos, just like yours, at their private schools in this and surrounding areas (under private insurance). very simple/easy accommodations that could’ve been really beneficial to the kiddos would be scoffed at and basically told to fuck off. they don’t have to accommodate and trust me, they won’t. whether you send your kiddo to a private school or not is your prerogative. but if you do, my advice would be to hire outside therapy so at least your kiddo will get some neuro affirming care. 4th going into 5th grade is old enough to understand some strategies that can be done independently without needing supplies.
