My 10yo son just expressed interest in a pump. What should I know?

He's about a year since diagnosis, and he brought it up at his endo appointment today, much to my wife's and my surprise. He thinks a pod style would be best as he is very active.

We're going to attend a pump-day at our local children's hospital, where pump reps all show off their wares. What do we need to know before making a multi-year commitment (our dr's office said it's typically 4 years, I think)?

What should we know as parents of a (potential) pumper?

(I have a basic understanding, and have read through Think Like A Pancreas, will have to go back and look at the pumping sections more closely now)
