Kids came on pumps with wild control. But I guess if you use it right it can be effective. It's so much easier. If you actually know what you're doing, you can sleep late without it affecting your blood sugar. You can eat almost anything, at any time.
Sports are no problem.
This summer I went to Europe, as an exchange student, and I don't think I would have been able to do it without the pump, because of the time zone changes and the erratic eating schedules. Then I went back to regular dosages. It was really a pain. I just kept it on American time on the plane, and when I got there, I changed the clock. Yeah, that was it.
