Question about child pornography

[Lambsbread]

I believe I read somewhere that federal law states that it is prohibited to possess a picture/video of a minor engaging in any sexual act.

Is this true?

Because, it got me thinking, if the law is that one cannot possess nude pictures at all of minors, then why aren't parents who post pictures of their infant children nude arrested?

I'm honestly very curious about this.

What's the confusion? You state yourself that the law prohibits possession of material showing minors engaging in sexual acts. Being nude is not inherently a sexual act.

I'm not sure if that's the law though.

So technically, enforcement of the law varies?

So basically it depends on the context of the situation?

I see.
