Mom told me that her relaxed attitude toward our bedwetting was a combination of experience, necessity and bluff. She tried hard to keep her worries from us kids, so that our bedwetting (and dealing with our bedwetting) were much harder on her than it seemed to me.
Mom confirmed the genetic aspect: She wet the bed until she was a teenager. (She didn’t say anything about Dad, and I didn’t ask. But my nieces and nephews on that side are late bedwetters as well.) It had been hard on her – waking (and sleeping) in a puddle, feeling shame and inadequacy, fearing friends’ discovery, hearing the contempt of relatives, avoiding overnight stays, smelling the odor that lingered in a room and on clothes. Her parents did not allow her to wear protection, believing that would remove the incentive to stop wetting. They tried all the available cures: Drugs, alarms, waking, no drinks before bed, …
Because of that, she knew that bedwetting wasn’t something that one could control. She resolved to be relaxed, sympathetic and reassuring to her own children, and provide us protection against a wet bed.
She wasn’t at all concerned that my sisters wet the bed as pre-schoolers.
When my oldest sister was about to start first grade, Mom raised her bedwetting with our doctor. He confirmed that it was likely not something my sister could control, and that Mom and my sister should not be too concerned. Some kids took longer to outgrow it. While there were drugs that sometimes provided relief, he didn’t recommend them for children. They weren’t a permanent solution and they had side effects. He didn’t recommend alarms or waking, either. Sleep is just too important to children. Unless she showed symptoms beyond just wetting the bed, the only thing he would recommend was to manage the consequences.
