My son used to wear his pump playing basketball and soccer. He used a sports pouch or a Spi Belt to hold his pump. You can use a hard plastic credit card to place over the screen so if it does get hit, it doesn't break or crack. We had an old gift card that was expired that we used. Your daughter will be fine and the exercise and activity is wonderful.... It just makes us mothers nervous. I know. My son doesn't wear his pump anymore to play sports although he should. We have come to a compromise now.... He is 15, and started Varsity soccer. He checks before he starts and adjusts accordingly.. then after 40 minutes of play, he checks again and reconnects and either gives himself a correction or at least his basal insulin rate....He goes very high when he plays sports and he needs to get the insulin in him. I would prefer he wear the insulin pump but he doesn't like it on and I know there were kids that would pull at it when he was younger...Good luck... It is worrisome.. I know !!
