My 11-year-old 5th grade son still has bedwetting problems. He's so used to it, it hardly phases him; we try to not make a big deal of it. Although in the last year, it has started to bother him.
As background, we've used the Malem bedtime alarm for years(!) with limited success. For most kids I think it works well, but it has been discouraging to still be doing a ton of laundry. He sleeps SO hard! So, a couple months ago, we talked to his pediatrician and came home with a prescription for Desmopressin.
We were all excited and created a chart to track the number of pills he took, hours of sleep, liquid intake after 6PM, and size of wetness spot in the morning. In the first week he had two dry nights and we were thrilled. However, the success has not continued. It is now a couple months later and we've only had 8 or so dry nights. So, I'm ready to talk to the doctor again.
My spin on this is that Kellie Y. might really be onto something here. However, the dryallnight website appears only in Scandinavian languages, not English, from what I can see. : ( (NOTE: Kellie updated me with the right web link...http://www.nobedwetting.com/. THANKS!)
I'm convinced our son's wetness is more of a sleep issue. He has always slept like a rock. There is also an emotional component to it, too, I suspect. He has been stressed about school for a couple of years now and is on the borderline of ADHD. We're about to start some family counseling to help him deal with some of the latter, but suspect it will help with the wetness as well.
Meanwhile, I'm going to try to get more info from Kellie Y. about the program they used. It sounds very on target at first glance!
