I abhore the term "dead in bed"! It sounds so cute and rhymey... like a dance move. I myself am plagued by nighttime lows (I'm talking 35 at 2am a few times per month, at least) even though I wear a pump and CGM. Remember though, that having a low sugar at night does not necessarily mean the dreaded DIB is around the corner. It's dangerous, but I've had diabetes for 33 years and I still always feel the lows a wake up when I'm well enough to fix the situation without outside help. In fact, I usually know I'm low before my CGM does. Your son may get low at night sometime, but that doesn't mean disaster is inevitable.
