For that matter, neither does an otherwise typical family photo taken at a nudist colony.
Which while indisputably true has generated some controversy in opening up an arguable loophole, some nudist resorts sell DVDs of filmed day to day activities featuring minors engaged in activities that are completely non-sexual but are obviously being bought by people who aren't just curious about nudism. Of course I'd consider this a far less offensive practice than child beauty pageants.
I wouldn't consider either pornography, and I have do have photos of neighbor's absolutely adorable granddaughter going to her
kindergarten prom.
