I haven't experienced traditional pumps personally, but Kerry at Six Until Me always talks about where she's going to snake her tubing through or how to attach or hide her pump (in her bra, in her sock, in her pocket). I think the PDM being separate is convenient simply because my daughter doesn't have to carry it on her 4 year-old body. With that said, my daughter has to be very close to me in order for instructions from the PDM to reach the pod; it's not as if she can be across the room or running around while I'm giving her a bolus. I'd say she needs to be within 1.5 feet. For those concerned about integrated CGMS, it's on its way! I think they are doing trials as early as this summer; unfortunately my rep said they probably won't use young kids for the trials, so I'll have to be patient. We've experienced the same highs after pod changes...right now as a matter or fact. But, as others have said, with a little trial and error (I've been giving a snack with an extra extended bolus or trying higher temp basals), that is improving.
