Bedwetting is a severe condition, my Mum has a particular procedure to make a child stop bedwetting, she has specific periods during the mid-night when she wakes up the child to go pee, the goal is that after some time, the child will continue to wake up to urinate at those specific periods, and of course, once your bed wet, you are ready to get some good flogging, so it sinks in your sub-conscious never to try it next time.
