I've looked at CSA / indecent images laws obviously, but they don't explicitly cover this.
Example scenario, your 2 yr old and the dog are playing in the (private) garden. It's hot and he's naked because you're in the middle of potty training. You take a photo of child throwing ball for dog. Child just happens to be naked.
You keep the photo for yourself and don't share it online obviously! But you don't want to delete it because your child looks so happy in it and it's a memory of a great day.
Have you committed an offence? If so would the police apply any exemptions because this image is only possessed by the parents and is innocent?
I haven't actually got a naked photo of my own children, but I definitely have a printed photo of myself from the 80s! I've also seen naked photos of a friend's kids, shown to me on her phone. Am I a criminal?
