hi @tmcconahay Mandy,
forgive me I am not a cheerleader. I think you could get a good idea of the equipment your daughter will wear on the medtronic web site. There are no pods with a medtronic pump system. a pod is a hockey-puck sized pump associated with the Omnipod pump system.
the pump in the medtronic system is a bit like an old-fashioned pager. it even has a belt clip. girls tend to put the medtronic into their pockets but I bet there are ingenious ways to hide the pump if something doesn’t have practical pockets.
the thing you wear on your skin is typically very small. here is a cartoon regarding one of the more populat infusion systems, the “quickset” https://www.youtube.com/watch?v=2Lu2Z8mYyzc
I tend to use my back-side for these and hitting it or making contact is never an issue. popular infusion sites include belly and back of arm. They stay in place like a “bandaid” with little or no extra effort. there are “IV prep” and adhesive tapes you can wear for reinforcement but to be honest, the adhesives make me break out and so I never wear them. I have only managed to “sweat” a few sites off in the last 12 years, and when that happens I just replace the infusion set. good luck with the pump.
