And, for me, naked children hold even less potential to be pornographic.
I have some friends who's two year old son is naked in a lot of pictures because they still have trouble getting him to keep his clothes on. Of course that gives them more potential to embarrass him when he grows up and it's payback time!
I agree with this (in caase it wasn't obvious).
There was some bro-ha-ha a few years back about the exhibition of a woman photographer's art - she'd taken heaps of photos of her nude kids, some of them posed, most unposed in various situations - swimming, going about the house etc. They were just kids, and they were naked. Nothing salacious, intimate for sure but mainly because it was in a famlity sitation and the kids were being - looking to be - happy normal kids doing their thing in a family setting. I thought the criticim of her photos as "potentially pornographic" was totally unwarranted.
But the Brooke Shields photo isn't a child being a child while in the nude - it's a child made up intentionally by
adults to be explicitly provocative/attractive (take your pick) to
adults. Complete with make-up, baby oil and a sexual attitude. A little Lolita if ever there was one. That is something entirely else than your friend's kid who won't get dressed.
I bet that this Brooke Shields pic has appeared in more than one of the "collections" found on peadophile persons computers, when the police arrest them.
The article I linked to says that Ms. Shields has tried to repurchase the rights to the photo in order to take the "art" off the market, but she's been unsuccessful. I think that's a pity.
