As a mom to a TEENAGE bedwetter (my daughter is 17) my suggestions are as follows:
Yes, some do grow out of this stage (though not in my case) - and other do not.
He can use pullups - or goodnites in the meantime.
I don't believe in the nitetime alarms if your son is such a heavy sleeper - in my experience, the alarms only woke everyone ELSE up in the house and not the bedwetter, and they corroded after a month or so.(even after thorough cleanings)(these are the alarms that clip inside the underwear so that when there is a presence of urine - an ear piercing alarm goes off to warn the bedwetter to get up and go to the bathroom)
I also don't believe in waking the child after they've been sleeping to go to the bathroom - if they are in such a deep sleep and you are 'dragging' them to the bathroom and making them go, chances are they won't remember going the next day. (in my experience this has happened)
I've used the following 'techniques'/'rules' :
no food/drink after dinner - eating promotes drinking - drinking promotes bedwetting.
Have your son sit on the toilet for 3-5 minutes every 2 hours - even if he says he doesn't have to go. Give him a puzzle or his gameboy or a magazine/book..etc...to occupy the time - the time spent on the toilet allows for his 'system' relax enough to go. Buy him a watch with an alarm and teach him how to set it to go off every 2 hours to remind him to go to the bathroom.
The last resort is the one I had no choice in making and that was to put my daughter on medication. DDAVP comes in a nasal spray and also a pill form. Ditropan is another medication in helping with bladder problems. She is on both and I'm happy to say hasn't had an accident in a long time! We've tried to take her off the meds only for her to have an accident and then go back on them. The doctor's say that her bladder is just immature and there's no telling when she may stop.
I hope this helps....good luck to your son!
