So, yes my family knew i was a bedwetter, but that didnt stop my brother from teasing me about it from time to time when not home, he was older and if he was with his friends and such would elude at minimum to even openly say i was a baby or i had a water bed or peed the bed, etc.
I usually didnt react or anything to it as much as i could but it usually did the job of me not being around him. So that was the goal at minimum.
But, other than my family, my best friend and thier family knew about it, as i would stay with them from time to time and also he would stay with us a well in the summer, usually for week to weeks, his family an my family both had cabins and in the summer i would usually not be in the city and at his or my family's cabins most the summer.
As it were they needed to know as had to deal with the bedwetting when i was with them and my friend did know too, and was just a normal thing and really never had any teasing about the bedwetting and as later in life when i was able to take care of it myself got to the point that i got my own diapers and took care of everything (rode bike to the store for them (and other stuff) made money on some side gigs when even very little).
But, after taking care of it myself to that degree my parents one day were "Proud" of my not having wetting issues, and i just left it at that and hid any signs of it and didnt speak of it for a good 30+ years and only came up as a side thing but wasnt a big deal when it did.
So, in middle school My mom usually did diaper me at night, and also they always kept my bedroom door locked at bedtime anyhow for sleepwalking (i'd get into and do some wierd things (still do) sleepwalkin, quite dangerous things, digging through knives, razors, cosmetics/meds, food, reorginize things in the house and creat havoc. I guess i did throw fits/tatrums when i'd getup and not able to get out of room (dont remeber as was likely sleepwalking) so my room was pretty clear of anything dangerous. So in reality i'd need a diaper at night, but i do know they would check in on me when they would hear me up at night, but.
So, till i was taking care of it myself (IC that is) it was the normal bedtime and diapered and the door locked till gotten up for the morning. After i was taking care of it myself, parent would still lock the door when they went to bed for the night, and that was just usual till like a year before i left home (moved) they talked to me about not locking the door, which TBH i thought was just normal and never thought about the door being locked.
Once on my own, i soon was working (didnt finish college) and was making good money doing contracting and soon also had a GF that knew about things too, then also personal assistants for work/personal stuff (quite often on local and one that went on the road with me) as needed that for work things and also used for sleeping/sleepwalking issues as well.
But as it were, after at parents, my GF's and also the kids knew about the IC issues at night and it was just a normal thing, i'd gotten some questions from 5yo's about it (as the kids told them) which i'd be honest as it was a medical thing afterall. So, my family, friends (even to this day), kids, all know about the iussues even the sleepwalking and alike. And often parents of kids friends would know, but i'm not going to lie to them about it for any reason, that isnt worth the effort to me.
I understand the want to not tell people, but in all reality family and anyone you might stay with for any length of time is going to know or find out, and when/if they do i'm honest about it. I also dont go around introducing my self as "Hi, I'm a bedwetter, and you name is?".
But, i also understant the more want to hide it if it's not entirely IC and there is some kink or ABDL in the mix as well, as it's not like people talk about thier kinks or sex life much.
So, I really think that anyone that is/was a bedwetter/IC will ever be able to truly hide things for long without a huge amount of worry and stress in the doing so (i did fo a few years so i know, but also my parents were not real attentive or snopping around types and were gone quite often and kids were left alone at a rather young age without any sitters). So hiding this from family for me is not worth the effort and stress to do so, and whilst i dont flaunt it, i also dont really hide it either and if someone asks or eludes to diapers i just am honest and it's never been an issues in either business or personal for me, as all my GF's have understood, but i tend towards women that are a bit on the kinky side (not abdl but other areas) so that would make them more apt to be accepting of it vs women that are more towards the vanilla side of things, I've never been intrested in the prim and proper girls myself, and am really more intrested in women that are very intelligent as well and not really traditional, but to each thier own.
So, bottom line:
Yes, anyone that sees/asks will get the true story and know i have IC issues.
Also, that anyone that is IC should NEVER feel like they need to hide a medical issue, it's no different than having diabetes or high blood pressure or chrons or IBS and should be treated just the same, its not your fault or a choice, its just how your body is.
Peace!
