I was planning on taking it out today anyway to see the skin, but we got a weak signal for quite a while then it went to lost sensor. Does this mean it was dead or could I have done "Find lost sensor?" I decided not to try so I could see the skin. Wow, his skin looked great. It looks good like when he used to wear the Navigator minus the temp probe spot. Now, I just hope it stays looking good on future sensors. I hate having two kids on different sensor brands but that is what we are doing right now. Had my son's Dexcom go to ??? for a while but came back. We are on the 2nd 7 days with that one. Hate to pull it he is sick with a sore throat virus right now. Came back from ??? with a couple point off BG stick.
