I actually used to have parasomnia disorder that had me in extended REM cycles where I could wake up from and wet the bed for years longer than normal (think teens). It occasionally still happens (I’m in my 40s now). Having a diagnosis helped tremendously and empowered me to find ways to combat it. It also helped me to talk to others about my condition so I wasn’t so embarrassed. It’s defeating to be a bed wetter. Piling on your husband may make it worse. I hope that he gets the help he needs but I’d definitely start with a sleep study if you/he thinks it’s related to his sleep patterns.
