First of all, Junior...
... you will not now, nor will you ever, call me "Missy".
Second, I quote you, chapter and verse, from your own post. No omissions, no elisions, only your words, complete with link, in case you have forgotten where you said it:
Children will sometime hurt themselves to gain attention. When they do this, it often works. The parents respond, so the child continues to hurt itself. The thing for these parents to do, as hard as it is for them, is to ignore the child’s behavior. When they see they no longer get a response, they will stop their bad behavior.
