I know we can use arms as sites, we are definitely going to push for us to do this as well as back end as right now she only uses the back end for her pump. I don't want to "chew" up her poor back end otherwise I also know about being able to leave a sensor in for 7 days. On the 7th day the transmitter shuts down and has to be recharged even though the battery life is good for 14 days. So we are looking at going 7 days tops and changing sensor same day each week. Every 3rd day we have to trick the system though and tell it is a new sensor. Does anyone have step by step directions on how we do this or is it the same as when you first start a sensor? I know about the radio shack microphone and web site where to buy it if we need it. We will try it without for now at first and see if it is necessary. We do have a baby monitor in her room. I did make up a pump/CGMS guide cheat sheet and gave that to the school nurse. I also made up user guides for her, Bio Mom and us in nice folders to keep. We have to calibrate at least 3-4 times a day, never calibrate when there are trend arrows. Don't have the pump away from the transmitter for longer than 40 minutes or it will alarm that it lost transmission. Then just put BG in and calibrate to get it going again if it does happen. Anything I said wrong or I need to know for tomorrow? I am getting nervous! Thanks!
