Hi! I have been a School Nurse and Camp Nurse for a few years. I would add to this great list some non-medical supplies. Safety pins, sewing supplies, eye glass repair kit, Contact solution. Also I have found that putting hydrogen peroxide in a small spray bottle is great for cleaning knee scrapes, etc, without having to "touch it". Other indispensible items include running shoes, a big heart, patience, and a sense of humor! Happy Summer....
