They get to play sports without worrying as much about going low. They get to eat what they want. They get to sleep in because they can let the pump manage their insulin. They also find creative ways to help work the pump into their lives. Instead of worrying about what other kids will think, some kids just let others think their pump is a pager.
Many kids even show off their pumps.
Pumps come in several cool colors, so you can have fun with them. They also come in waterproof models, if you need them, although most kids don't. If you want to swim, you can just disconnect the tubing and store the pump in your bag or locker. To take a shower or bath, you can disconnect the tubing, or you can just use a longer piece of it and let the pump rest outside the shower. When you sleep, you can just put the pump under your pillow or on the bedside table.
