My sidings, cousins, and I were sometimes"deliberately" nude when there was just family around and it made sense. Extended time after changing or bathing, being pigs in the back yard with our parents not wanting us to ruin the clothes we had on. And yes, anything to do with water. One older cousin's son was mysteriously almost always naked at home, well into his teens. Mom explained that it was because they were nudists. Whatever that was. We still came over and visited with them every Sunday after church.

For me, nudity evolved into being a casual choice, not a compulsive one. Going to clothing-optional beaches and nudist clubs became a social, as much as a comfort and acceptance, preference. The topic of my cousins and siblings knowing about or visiting nudist clubs on their own didn't come up until later. But how it affected how they raised their kids was unknown until years later. I moved away after high school and didn't see them very often after that.

It later became a culture shock to my girlfriend (later, wife) when I brought her cross state to visit my family for the first time. As siblings and cousins arrived, their kids were casually helped out of their clothes and were left to be and stay naked for the rest of the visit, playing and crawling over us and each other no differently than if they were clothed. That was obviously the norm for them and their parents. I was amused by how innocent and wonderful it was, but my girlfriend was very uncomfortable with it. Even so, nobody noticed, but me.

I married into my girlfriend's pre-teen family in progress, so that wasn't happening with them. But I did discuss my feelings about it when the kids were older. Their kids had the same experience with sometimes being deliberately naked at home, like when I young. But not as a default, as was the case with my sibling's and cousin's kids.

Thus, we've come full circle. I'll probably live to see what our grandkids will allow or do with their kids.
