You may be struggling to understand how a shooting could occur and why such a terrible thing would happen. There may never be satisfactory answers to these questions. As a parent, you may be struggling with how to talk with your children about a shooting rampage. It is important to remember that children look to their parents to make them feel safe. This is true no matter what age your children are, be they toddlers, adolescents or even young adults.
