That being said, it's hard to really regulate this. When someone has a baby, they usually share a photo in a public manner of the entire family. It's hard to argue that parents shouldn't be able to share any pictures of their family in a public manner. It also would then prevent journalists or anyone for that matter, from taking pictures in public spaces that contained any minors... which starts to get absurd.
Hopefully my kids will appreciate that we never posted pictures of them publicly on social media (only shared privately within immediate family). At the very least, it's one less thing they'll have to worry about as they grow up.
The trick is to live like it's 1980. We have many, many pictures of our child, but only 10-15 on social media (of things like winning sporting events or the like). Everything else is in digital form on drives in our home server or printed in physical frames. If/when the child decides they want to do something with their photos, there they are.
Also handy to have on the home server because we can turn any screen into a digital frame on our network. That will be great when they bring their first boy/girlfriend home.
People just feel the impulsive need to share literally everything on social media. Everything is a competition for likes and attention. It's disgusting.
I'm also not talking about someone sharing a photo publicly with someone else's kid in the background.
I just mean as a parent you should need consent to share a video of your kids to a public social media channel. If your kid cannot give consent because they are underage or refuses, then you shouldn't be able to share it.
I'm afraid not a lot of parents/people would be willing to pay for such service, so I'm unsure this is going to happen any time soon.
In practice no politician will want to be on record as the cause of child safety ratchets being relaxed; and so there is no realistic path from the current environment to one in which a person may become free to act as they see fit with previously problematic images of themselves on reaching majority - the trend is towards such images being seen as problematic purely based on content, regardless of context.
Point is there should be a way to limit public sharing of photos and videos without a child's consent. There should be a good reason, beyond a parent's own narcissism.
There is an application in CA for an entertainment work permit, but that's mostly validating age and satisfactory education status (for school age children) and medical clearance (for infants under 1). So, I think the analogy doesn't work and you should work out what kind of application you mean here.
Children have the right to privacy, and it is crazy how many parents do not think twice before sharing.
