S.B.
My brother and I both started bed wetting after having a few years of 'dry' nights. As far as I know it was never linked to anything emotional - I didn't stop until I was 17 or 18.
I too was dragged to doctors and tried everything - withholding drinks after 6p, stopping caffeine, nothing worked. I think for some of us, it's just a slow development of that control mechanism.
Now, my son's bedwetting has improved since he had his tonsils out. Since neither my brother or I had our tonsils out I wonder if we too were suffering from sleep apnea and were just sleeping too soundly to wake up until we grew into our tonsils.
The doctor says he never makes the claim that it will help but he has heard often of improvement in bedwetting when children get their tonsils out.
