Children are very resilient--but they are not unbreakable. No matter what their age, children are deeply hurt when they are physically, sexually, or emotionally abused or when they see or hear violence in their homes and communities. When children see and hear too much that is frightening, their world feels unsafe and insecure. This brief report describes: (1) What happens when children are exposed to violence; (2) The warning signs of exposure to violence; (3) What teachers can do to help; and (4) How to know if more help is needed.
