Here in the Netherlands a new children's TV program started: [0], kids ask naked people questions. I applaud it, finally, a source of naked that is not porn, The kids ask stuff like: "What are you most ashamed of about your body" and things about new hair growth they are about to experience, not even sex so far. And they get to see realistic penises and breasts while they are learning.
I guess I'm finally starting to understand why I like old Dutch movies like "Turks Fruit" [1]. Or modern non-US series for example from Spain, where people have sex (even in their 40's omg!) and go to the toilet, and where women are strong. I like Casa de Papel for example, Raquel is very sensual, intelligent, funny, flirty and strong, and usually fully covered in clothes, perhaps the antithesis of this new asexual trend. It's refreshing and normal and liberating. Of course it helps that she like's the nerdy "Professor" ;). Although this nerdy professor can, in contrast to all stereotypes, flirt quite well ("Intelligence can be very sexy") and knows how to engage with her. Also: refreshing.

I now do the same to my kids. The key is to do it from day one, so there is never that first memory of “when did you first see your parents naked”. There is no first because it’s been always. There is no shock because it’s perfectly normal.
Because you don't look at your family in a sexual way. Similarly in Renaissance, for example, we had some nudity going on in art, but it was done in a tasteful and non-sexual fashion. That's different from outright pornography or erotica, which is what children should not be exposed to.
Like the parent commentor said, it's probably about experiencing nudity from day one. I grew up in a family where you'd never see someone naked, but then, as a teen, was exposed to a family that's comfortable with being naked around each other. I had some readjusting to do, because for me nakedness had become something super private, dirty and sexual. Now that I think about it it makes me kind of angry that I grew up with such a stupid outlook on the human body.
Could you say if this was a fixed behaviour (ie they always sought a private place to poop), had a fixed location (eg always behind the couch), if you used a potty at the time, and exactly which month it appeared at so I can note it with my own observations. Cheers.
Mind you, I've very much been a late bloomer so my perspective is probably not representative.
I think this is a (the?) fundamental issue here; you're beginning from a place of needing to be told its OK to be naked near a child. That there needs to be a strong reason, a defensible argument just to have no clothes on near a child. There's an assumption in this thinking that by default, it's simply bad to be naked near a child - an assumption that's entirely cultural and learned. Cultures that don't have this hang-up don't have a strong argument for it - they just think it's crazy that your culture is so weird ("WEIRD", one might say) about it for no good reason.
