I would recommend steri-strips, benadryl, vicodin, anti-diarrheal, tweezers, needle (for splinters), empty syringe for irrigation, gauze, tape, moleskin, tampons and that's about it.
Sorry, just read the scouts part and you would be put in jail for giving a scout vicodin. Advil liqui-gels instead then? Splint material is pretty easy with sleep mats and duct tape. For bee stings/allergic reactions, crush a bunch of benadryl and feed it to them if they don't have an epi pen. I really do like to keep all my med gear in an op-sack though because wet gauze is bad news imo.
