Bedwetting Support Group
Bedwetting (or nocturnal enuresis or sleepwetting) is involuntary urination while asleep. It is the normal state of affairs in infancy, but can be a source of embarrassment when it persists into school age or the teen or adult years. Find others who are coping with a bedwetting problem and share your experiences and questions.
Depending on where you are located he might qualify assistance if you're in Europe it is the "NHC" i don't have much experience with them but have resources here in the US if he is on Medicaid then he might qualify for free diapers/pull-ups depending upon the state. Feel free to message me I work as a Special needs Navigator in my county as a local Homeless shelter for families and on Facebook dosing Parent to Parent support.
I hope this is of some help "Steve"
