It sounds like you've made great progress BSM - great work advocating!
LBS is learning behavioral specialist, and is dedicated to DS's program, since there are several ASD/ IEP kids in there. But she just doesn't seem to get neuro-diversity at all, and expects all kids to be pretty much the same. I think she makes honest efforts, but unfortunately, her skill set is limited.
Do you know what type of training she had? Can you request specific training for the next LBS?
I'll also be hoping for an early delivery
Best wishes,
