This is a fabulous, well-worth-your-time read on Parents.com. The post was written by Wendy Sue Swanson, a pediatrician mother who describes her emergency kits and plans for her kids. She has a lot of great ideas.
I thought her idea of writing a letter to her son (to keep on file at his school in case of an emergency), was particularly smart. She included it on page three of the article.
