1. A recent, clear photo. Updated every six months for young children, since appearances change fast. Include a front-facing photo and, if possible, one showing a distinguishing feature like a birthmark or scar.

2. A current physical description. Height, weight, eye and hair color, and any identifying marks, written down rather than relying on memory in a stressful moment.

3. Fingerprints, if you have them. Many local police departments offer free child ID fingerprinting events. It is worth doing if one is available near you.

4. Dental records contact information. Not the records themselves necessarily, but the name and number of the dentist, which investigators may need to request directly.

5. Medical information. Allergies, medications, and your pediatrician's contact info, in case of injury during a search or recovery.

6. A list of frequent locations and routines. Where they walk to school, favorite parks, close friends' addresses, anywhere they might go on their own.

7. Emergency contacts beyond you. A second and third person who could be reached if you are the one who is unreachable.

Keep it somewhere you can grab quickly, and make sure at least one other trusted adult knows it exists. Savor's In Case I Go Missing Binder uses the same envelope and label system as their other document organizers, with labels specifically built for this purpose, so the categories above are already laid out rather than left for you to design from scratch.
