This is a very interesting thread. I have a 21 year old daughter that was disgnosed early on with autism, but she was not a typical case... later her diagnosis was changed to Rett Syndrome (kind of related to autism, but occurs only in girls), but also not a typical case of Retts. She is very low functioning, we have to do everything for her, she has a feeding tube, no communication and is in a wheelchair... but other than that, she is always healthy and seems happy. She has seizures that can't be controlled no matter what meds she is on. She is currently on three and still has several seizures daily. I had forgotten about these weighted blankets and now I am wondering if one would be of any comfort to her. Hmmmm.....
