"I note that the "therapist" has not been named. I'd be interested in knowing that name, so I could do further research."
Ouch. I read the article Rodney King posted re: "Attachment Disorder" and "Attachment Therapy." The fact that the family is operating under a diagnosis that is generally regarded as quackery is a warning bell.
The diagnosis given by the family is I believe RAD which is recognized by DSM. The quack therapy described was for AD.
