Check your first-aid kits regularly to be sure the flashlight batteries work and to replace supplies that have expired or been used up. Mark your kit with the date last used. Kits may go years between uses, and some contents may expire.
Consider taking a first-aid course through the American Red Cross. Contact your local chapter for information on classes.
Prepare children for medical emergencies in age-appropriate ways. The American Red Cross offers a number of helpful resources, including classes designed to help children understand and use first-aid techniques.
