D., this is really personal to me. I myself was a bed wetter! I tried everything, It started when i was 7 years old, night terrors would not allow me to awaken, I tried alarms, pills, i even tried the no drinking after 6PM, the problem was, i was dreaming in such a deep sleep, that i thought i was getting up and using the restroom. Only to find out, that I was still in bed, it was embarrassing, I was spanked, sent to a counselor! Nothing but time helped me. I can only suggest adult diapers at night, and all the loving support you can give, also my bladder is tilted and spasms alot. Just something to consider. I no longer wet the bed, but if im not careful, in my deep sleeping episodes, I have come close, I am almost 38 years old, and have high hopes your two great kids will get through this! Be positive, and compassionate to them. It must not be easy for you, but for them its devastating!
