You're right - she might do just that, glad you thought about that. It'd be nice if she had some support herself - but you don't want her giving the two of them this piece of gold thread you've got here!
You don't think, with DB on your page, that she'll search this and find this anyway, do you???
Maybe you can at least recommend some books and other materials for her. ???
Try to give her a break, because of her age, lol. (I know it's got to be frustrating to not have a competent ally that you thought you might have.)
