Hi H..
A product for waking a night wetter is sold at One Step Ahead:

I have not used it, but saw it in their catalog.
I wanted to mention a friend of mine had major difficulty potty training her 4 year old daughter and found out it was a sensitivity to wheat that caused her daughter to not be able to hold her pee long enough to use the toilet. Apparently, some food sensitivities can cause an irritable bladder. The most common food sensitivities are wheat, soy, dairy and nuts. You can search the internet for more info. It's a big job to determine if this is the issue -- you have to eliminate the offending food from the diet for 2 weeks and see if there is a change. That can be really challenging with wheat and dairy. Good luck!
