Sorry... you're saying a baby feels trauma and shame when it has its picture taken and that leads to psychological problems as an adult and creates more trauma when you show that photo to their partner?
Also, virtually every new parent has photos of their baby naked on their phone. And it's legal. I have no idea why you don't think it would be. A nude picture of your own baby is not child porn. No one has ever been put on a sex offender list for having a picture of their child just after it exited the womb on their phone. What a silly thing to say.
