I'm so sorry you are having these problems with your youngest daughter. Can I ask, do you have your daughters in therapy? If so, you might write a note to her therapist to let him/her know what is going on, so they can address it. If they are not in therapy, you might want to consider it. Abuse can have a very big affect on kids, and they need a chance to process it, and won't always do that with their mom.
