did some more checking all states in the USA designate babysitters as mandated reporters. that means when someone is or has babysat someone child, teen or adult and they feel the child, teen, adult is in need of special services, or in need of mental physical or educational services that they are not getting due to many reasons must make a report to the child or adult protective services in that childs location or through the national hot line system. After the report is made an investigation is done to see if the child\teen\adult is being neglected or abused in any physical sexual or emotional way. if so action is taken (action means either the one doing the neglect or abuse is arrested and prosecuted and the child \teen\adult in need of a babysitter\caretaker or otherwise supervision is remanded over to inpatient or outpatient services that fits that child\teen\adult needs such as foster care, hospitalization or other inpatient\out patient residential services that fits the neglected\abused physical and emotional needs. )

my suggestion is if you really feel this friend needs help that they are not getting and want to help the best thing you can do for this person is make your mandated report, then let the police and child protective services do their job of investigating and getting her the help you feel she needs.
