I have an 8 & 12 year old still wetting the bed. The 8 yo is my daughter and her accidents are maybe 1 or 2 times a week. The 12 yo is everyday but he is my step son. I have been told the earliest he can stop is the age that was the youngest for his parents which was 12 and he could stop up to the age of the oldest parent which was 17. He has always hated wetting the bed everyday so we put him Good Nights but he wet through every night. Then we moved to Depends. He still soaked through every night. Finally after 4 years of dealing with this (how long we have had custody)He was so frustrated and his father and I were too we took him to the doctor (we made sure this is what he wanted). Anyway, the doctor put him on DDAVP and we have had NO accidents since. His self esteem is so much higher. The doctor told me they will not treat until the child is 8 or has an esteem issue concerning wetting. Before doing medication we tried EVERYTHING. I went to the library and read up on bedwetting. Some suggested it is the diet of the child so we altered his diet and nothing. We cut off everything after 5 and nothing. Tried setting alarm clocks but he never heard it. I went up and woke him up but he was a sound sleeper and he would go to the bathroom and literally fall asleep on the toilet. It was miserable for all of us. The DDAVP has been a lifesaver. I know many people are opposed to medication but there comes a point where you have to say to yourself, "What is BEST for my child" and put your feelings aside. Bottom line is, what does your child want? Does your child want to stop wetting the bed? Is your child embarrassed by this? If you can answer yes to this then I suggest you see your doctor for advice. If medication is the answer I recommend DDAVP.
As for my daughter, she is occasional so I am not too worried about her. She is not bothered by it either. I know she will eventually stop and it is not an everyday thing. As long as she is not bothered by it I am not too concerned. When she worries then I will worry. Best of Luck!
