Have you looked into Kerri Rivera and MMS?
You should check it out. I'm a special education teacher and have worked with lots of kids with autism. I can't recommend it to my students because it goes against mainstream science & public schools go crazy.
I can tell you from firsthand experience that MMS is VERY, VERY powerful and from what I've read, I think Kerri Rivera is legit……although I can't verify. She's changed a lot of people's lives by helping or curing autism.
