If you are looking for a local first aid/CPR course or a babysitting course, the American Red Cross here offers classes here on base. Just contact the ARC at 02451-63-2068 or firstname.lastname@example.org for more information on classes, cost, and times.
The ARC is a volunteer organization – usually manned by just one volunteer here, so be patient. The office is not staffed daily and classes are offered as demand and the availability of a teacher exists. If you have a child 11 or over who wants to take the class, go ahead and let the ARC know so that they can look for a teacher and see what the current demand is for a class.
