For those of you with kids in school - I am trying to figure out the minimed CGM calibration. If you insert at A 9 PM on a Sunday, calibrate at 11:00PM on Sunday - then it needs another calibration in 12 hours - correct? What happens if you child is in school and it wants a calibration? Do you just say yes? Or do you try to use a different schedule system than this to get the calibration at night when you are home? Trying to figure this all out!
