I had a friend do this with her son who has Aspergers. They saw really good changes with his social-emotional abilities and tolerance, and other behavioral and cognitive benefits with the first round. Teachers, therapists, friends- everyone was wowed, so they went ahead with another round which ended up causing him a lot of difficulty. If your child is showing any backwards movement, I'd probably withdraw early. Two others I know have had mixed benefits. Also, look for a "chiropractic neurologist" - they essentially do many of the same things and may be insurance covered. I believe Dr. Mellilo is also a chiropractic neurologist, but expanded and packaged it into the BB program.
