We used well placed baby monitors (with permission) for her bedroom (not the camera kind just audio) magnetic door alarms (the kind that beep when doors open and close) to track her. She was still not safe around our then 18 month old dd. Our preteens were not in any danger though she would occasionally self stimulate in front of them (if I went to the bathroom with the baby or put in some laundry with the baby etc). Our fd is in rtc but although we love her deeply it was a rough nine months. In addition to the sexual stuff there were more behaviors.
My heart goes out to the kids and those caring for them. It's tough. A good therapist helps but you can't bring them home with you. If you can manage to get a specialized care rate I am a huge advocate of hiring some help to help supervise!
