I wouldn’t even say “before relatively recently” as it depends where you are. Up until my daughter was like 5 or so she was just fully naked or in a swim diaper at the beach and like you say nobody considered that to be “nudity”.

But we’re in rural Canada where we don’t have the pedo paranoia that seems to have taken over America, and we just let our kids run free like we did.

Though it’s growing in the cities and small towns now, not long ago in a nearby town there was a Facebook panic over a man in a white van driving slowly around town. Unsurprisingly he turned out to be a plumber looking for the right address.
