Naps and Bed Wetting

I was listening to doctor radio on XM/Serius on my way to lunch and a pediatrician was talking about how, if you have a baby who wakes up a lot at night you shouldn't let the baby nap during the day. Sounds like Duh. What was interesting to me was his explanation of how naps affect the sleep cycle. I guess naps are special because for some reason with a nap the body dives straight into the deep sleep (rem3) cycle which it doesn't necessarily do when you go to bed at night. The baby napping in the day is using up its needed deep sleep time so when something bothers it at night it wakes up instead of sleeping through it.

This got me thinking, if you have a child who sleeps deeply so as not be woken up at night by the urge to pee, one solution might be to make that child take a nap during the day and use up some of that deep sleep time. In theory the child would need less deep sleep, and spend more time sleeping at a shallow level, where they might be able to wake themselves.
