My son's calls for MDI are starting to resonate. Today at school the PDM crashes. At first it re-booted and began asking for name, time of day, etc .... When I get to school to reset basal rates etc ... the screen begins repeatedly flashing from all black to all white. All black ... all white. Couldn't shut it off. Tried rebooting, per Insulet's suggestion. Nothing. Broke the old PDM and pods out of the closet. They're over-nighting another one. Up to this point I've resisted his calls to go MDI and convinced him and me that the pump is the way to go (he won't consider tubed). I had to talk to him AGAIN about the benefits of the pump over MDI but "the sell" is getting tougher and tougher.
