Were you even in the room with your newborns? Both of mine were moved to a table, cleaned up, and swaddled. I would have had to literally interrupt them to take a genital picture of them.
But I guess where you live, they pause first and ask if you want a full naked body shot? Cool tradition, I know you love those.
I'm sure noone has been in trouble for ONLY having their naked child's pictures on their phone, but I'm sure those pictures have ended up in CP collections. I'm sure you have perfect opsec though so its fine.
Legality as side, since its not the law preventing me from abusing children anyways, I'm arguing that its morally wrong. Plenty of immoral actions are legal from my perspective.
Why does your perspective need baby genitals to be featured again?
