This webpage from the Office of Human Services Emergency Preparedness and Response provides information and links to resources for helping children during and post-disasters. "Natural and manmade disasters can happen anywhere and at any time. In recent years, our country has seen a steady rise in the number of large and destructive disasters. In 2012 alone there were 112 disaster declarations, totaling over $85.7 billion in economic impact. Ensuring that all Americans, especially those with young children, are prepared for disasters is a top priority of the Department of Health and Human Services. Because of this, HHS has developed and compiled a rich set of resources that will help families, early childhood providers, and policy makers prepare, respond to, and recover from all types of disasters. This comprehensive set of resources contains interactive activities to plan and prepare for disasters, developmentally appropriate books and games to help children cope after disasters, and State templates and guides for policy makers to use in developing, enhancing, or improving their State plans. Check out the page that best fits your needs below."
