how to adopt my grandson

This message was originally posted by [url=http://forums.adoption.com/old_boards.php?username=Ren035]Ren035[/url]. My sixteen year old daughter has decided she doesn't want her 5mo. old son. Which I think is for the best. She has been recently dignost with borderline personality disorder. Which she goes into rages and at times can't handle reality. I want to take full custody of Jordyn but I'm not shure how to do that. Can anyone help
