Help! What am I doing wrong? My daughter's Dex is only vibrating when she goes lower than the setting I have for her low alert. I can't sleep at all now, she just started pumping so as we're messing with the basals and insulin sensitivity settings etc..so I really want Dexie to be alerting me for lows. I have turned the alert to "disable" and then turned it back to "vibrate and beep" and it can beep and does when I do that but it won't actually beep when she is dropping below the level I have it set at. Any help would be GREATLY appreciated. Thanks!
