there's a chance, if I ever get it off of her today that it could be laying in the street outside my house. I am at my wit's end. Her sensor was on day 4 yesterday. We have had the last two last 6 and 7 days. I did cals at 1am 8am and noon - pretty typical. It was off all day long. By dinner time it was reading 68 and her meter was 110. Through this time she had arrows so we didn't try to cal again. At bed time reading was 120 and she was in the 200's. After putting her in bed we got one alarm after another, ending with bad sensor about 2 am. I slept through my 3 o'clock check and didn't wake up until this morning. Thank God she's ok. And of course, I found myself missing the fact that she had something on her that would alarm me if there was a problem. What are we doing wrong? Why am I having such bad luck? Is she so truly unstable all the time because of her age that it can't get a great reading? Is there such a thing as a bad sensor or a bad lot of them? I like the idea of the sensor - I just don't understand why it's not working for us. I figure if all of you love it and I don't then it must be operator error? Before telling me anything about calling the Minimed nurse, I will say that we are BY FAR the youngest with a sensor and they don't offer us any information. It's sort of like we they don't want to be liable for anything that goes wrong.
