You will need a finger pricker, test strips (even if your child is on a Dexcom CGM), a pen or an insulin vial or two (in case one goes bad), fast acting sugars for lows, syringes in case you need to inject insulin, alcohol pads to wipe down skin, either Glucagon or Baqsimi (for emergencies), and extra insulin pump supplies in case a pump goes bad or expires).
Make sure you have your insulin, a finger pricker (even if you have a Dexcom GGM for your child) – we love the Genteel Gentle Lancing Device, test strips, a glucose meter, extra needles or syringes if you need to use insulin out of the pen or vial, tape for the insulin pump or Dexcom, extra pump or two, low supplies (juice, GoGoSqueeZ, glucose tabs, fruit snacks, candy – fast sugars), alcohol pads, hand sanitizer, and either Glucagon or Baqsimi (for emergencies).

Laugh if you must, but these are great for kids to carry their pump, phone (or Dexcom receiver) and a small fast acting sugar snack.
Kids will still have to carry the essentials I mentioned above in a backpack, but this is a good way to quickly be able to grab a phone to see a blood sugar reading or to check their insulin pump.
