So...tonight we had our first alarm goes off on Mia's pump - this was not a simple battery alarm noooo but a CALL SERVICE/NO DELIVERY Alarm....oh, this scared the heck out of me!!!!! We didn't hear the sound despite it being set on high but Mia jumped out of bed when the pump started vibrating as well. I guess there is an auto-fallback if there is no response to the sound of the alarm, the pump starts vibrating after 10 minutes or so. Wow, I realized just how much (Mia's) life depended on the pump. I also got nervous about the thought of having to get back on shots if something was wrong with the pump. I was so scared when I called Animas but they told me it needed a simple "reboot". Oh, what a relief!!! This experience raised another question though: What if the alarm goes off in the middle of the night and we can't hear it?? What if Mia sleeps through the vibrations??? How do you deal with that? How often do they occur?? I am (and have been since diagnosis) testing Mia at midnight and 3am so there has never be more than 3-4 hours before the next check but I hope that I can skip a middle-of-the-night waking at some time in the future. I would love to hear others' thoughts and experiences on this subject.
