I'm glad to see all of the comments on this issue. My 4YO son was a late potty trainer - didn't regularly pee or poop in the potty during the day until well after his 4th birthday. He just wasn't bothered by wet or soiled clothes or pullups - too much to do, I guess. Unfortunately, he's carrying that into his nighttime training, which is pretty much zilch. He's been sleeping in underpants for a couple of months now, and wets the bed 9 nights out of 10. He sleeps right through it, and gets up in the morning and plays in various locations in the house (sometimes sitting on the couch and whatnot), completely oblivious to the fact that his jammies are soaked in urine. We're against putting him back in the pullups, partly because of the cost and partly because I want to believe that he'll train faster at night if he wets the bed than if he can pee without consequences, like in the pullup. Otherwise, we're pretty much at a loss. It's getting REALLY old having to wash his sheets and blankets every single day. My wife and I both work, and having to devote all of the available laundry time to my son's soiled blanket and sheets is growing to be rather taxing.
