Bed Wetting What Should I Do About My Sons Bed Wetting?

What should I do about my sons bed wetting? - bed wetting

My oldest of three children started wetting the bed. He was 14 We saw the doctors and said he would spend a few months. But it was more than three months and he said that I think about to buy diapers for my son. I do not know if you will, but it is the only way to dry things out. Then I put diapers and if so, what kind and what brand? Even though I do diapers How do I ask them to bear? Please help!
