I was a teenage bedwetter...not all the time but it could happen at any time without warning and mid teens 14-18 y.o.. I guess you could average it to about 60 nights a year happening in clumps mostly. I'd be anywhere from damp to properly wet when it was happening . What tended to trip it more often than not was trouble with an alcoholic family member , school , some personal health issues etc.
Mum insisted on me using a nappy and overpants and mattress protector during these times and having two younger siblings that had no such problems made it tough but just how it was,, I ended up using towelling ones that Mum made (about 10) and used some plastic overpants meant for elderly folk and a heavy plastic mattress cover to help my parents minimize the staining of sheets etc...nothing bought except the overpants ..
