police shut naked child photo exhibit, page-29

I think the context of the photos needs to be considered as well

We have countless photos of out kids when there were toddlers running around naked at a beach somewhere.

the photos were taken of them having fun at the beach, they just happened to have no clothes on them at the time because they were playing in the water. They were not undressed so photos could be taken of them naked.

And I Do not think they would do the same thing now they are a bit older nor would I want them to.
