I have 4 children, 2 of which were bed wetters. My son was the worst, being an almost constant bedwetter until he was 10, then it decreased in frequency. He "magically" stopped at about 11 1/2 and has never had an incident since (he's almost 17 now). My daughter was a bedwetter until she was almost 9, then again, "magically" stopped. I learned with my son that all the little gizmos and gagets to stop bedwetting did not work, I also refused to give him drugs (as the pediatrician suggested) to stop something that was not life threatening or altering. It was hard but, learned to smile and say thank you to those family members and friends who meant well with their advice too. Bottom line, he grew out of it, so did my daughter.
The issue was more mine than theirs and when I got upset or hung up about it, then they did. The best advice I can give is to NOT make a big deal out of it. They will outgrow it. The issue is more the parents' because we have to do the clean up. Again, it was difficult, but I learned to "mellow out" and accept the bedwetting for what it was...part of their growing up process. I had my son and daughter be responsible to make sure they went to the bathroom before bed each night, put on their 'goodnights' AND if there was a leak to the bed, they had to bring me the sheets in the morning. We made it just a way of life. We talked openly about it in our immediate family, even with my other two children. They all were very aware of how this issue would be perceived by children and adults outside of our immediate family, and knew that it was no ones business to know but ours. It wasn't some deep dark secret, we handled it like most would any other family issue or illness, privately.
