Internet trolls freaked out over a nude photo of a 4-year-old boy and forced Peter Davis, publication director of the Daily Front Row, to delete the image from his Instagram account.

The photo — showing Davis and the boy’s mother (Davis’ friend) holding the naked toddler in their arms — was taken in an outdoor shower in Montauk after the three had been swimming in the ocean. The adults are wearing swimsuits in the photo.

“We all washed off the salt water . . . and his mom wanted to snap a photo. Obviously we were not trying to exploit a child, much less a mother exploiting her son who is the best kid you can imagine,” Davis told me.

Davis posted the shot on Instagram, where he has 42,000 followers — many of whom took offense at what they considered to be child pornography. Davis quickly took it down.

“We are living in an age of the political correctness police and anyone with an ability to comment on an iPhone wants to play judge and jury,” Davis said. “I am sad that a sweet moment of a mother and her child post-ocean was twisted into something it was not and never would be.”
