You have a moral, and in some cases, a legal responsibility to see that child abuse is reported to the people who can help. By law, you cannot be prosecuted for doing so in good faith. First, be sure you know the fact then act.
BE A FRIEND: Often an abusive parent needs someone to talk to for advice and support. Do your best to offer a sympathetic ear and to suggest services (social, medical, etc.) that can help. CONTACT LOCAL SERVICE AGENCIES: The Child Abuse Hotline, 1-800-540-4000, should be called immediately to report child abuse or neglect. People, who must report child abuse, often referred to as Mandated Reporters, vary from state to state – usually they include physicians, dentists, police, school counselors, teachers, nurses, etc.
