Bags with zippers or Ziploc bags are the best options.
Put a name tag/ID card and a picture of the child with their family inside of the emergency kit.
Buy small plastic water bottles instead. There are mini bottled water kits that you can buy in stores.
Granola bars and crackers are good options. There are nut-free granola bars (which contain fruits like figs and raisins), so if your school doesn’t allow foods like nuts or seafood, bring nut-free granola bars or foods instead.
Bring inhalers, Epi-Pens, pain medication, ADHD medication, diabetes blood glucose meters and pumps, and other important medication and put them in the kit.
Buy a mini flashlight. You can buy these in most stores. Large ones wouldn’t fit in your kit, and they would waste too much precious space in your emergency kit. You should also pack extra batteries in case the flashlight runs out of battery.
Pack wet wipes (to sterilize wounds), band-aids, cold compresses, gauze, bandages, tweezers (to treat splinters), medical scissors, and a thermometer in addition to the other supplies.
