The fears you have make sense to me. I think I'd have similar ones, though mine has grown out of the yelling part in old age. I can't imagine her agreeing to it anyway. I'm curious that a t would agree to do this with people since it seems like the t would naturally be a bit on the side of the child (you) since you've been talking to him for longer. (Not that the t wouldn't have other good reasons for being on your side as well.) I know t's work with families but guess I thought the child would have to be a child still. Sorry I don't have any advice but good luck if you try it.
