I am sorry you are having to deal with this issue. I so agree with those who say be very careful, she WILL try to take you down with her. It is not a deliberate thing, it is a part of the sickness. The best you can do for her is to provide her resources in her community and if you believe the child is in danger, call authorities. That's a hard thing to do, one that I have had to do more times than I remember. I am a mandated reporter, you are not legally obligated, but certainly want the best for the child. If you don't know what resources are available you can call the United Way. I think in most parts of the country the number is 211.
