We received DS Dexcom yesterday! We are not in too much of a hurry to use it. I want to get a better grip and go back and read through many of the threads I've missed to ward off any mistakes we will make in the beginning. Do you have any extra hints or tricks that work for you? I've read that you can trick the sensor into working past its expire date by restarting. How long is it supposed to work? Whats the longest anyone has used a restarted sensor? During bath-time, or anytime rather, is it best to cover the sensor with IV3000? How water tight is the sensor? DS is 2 1/2 so I'm sure we will use his bum for CGM sites as we do w/ pumping. Is there much of a difference between bum and tummy as far as results? I'm reading the Dexcom inserts it came with and I'm about to do their online tutorial again. DH and I are going to try it out first and then we will use it on DS on a part time basis to start. We want to take it slow at first. Right now we are not in a rush cuz DS #s have been really good lately and pumping is going very well.
