A friend of mine has a coworker going thru this with his pre-teen son -- no cf. And apparently, the coworker had a similar problem. Apparently, the kid sleeps so deeply that he doesn't wake up at night to pee. The parents set their alarm and wake/sleepwalk the kid to the bathroom in the middle of the night. Think there are also "big kid" pull ups or something (pad) that can be put in the underwear in case there are accidents.
