From an older (February, 20190) piece in The Atlantic, about kids finding out that their parents has been sharing their life on social media since their inception:

For several months, Cara has been working up the courage to approach her mom about what she saw on Instagram. Not long ago, the 11-year-old—who, like all the other kids in this story, is referred to by a pseudonym—discovered that her mom had been posting photos of her, without prior approval, for much of her life. “I’ve wanted to bring it up. It’s weird seeing myself up there, and sometimes there’s pics I don’t like of myself,” she said.

Every parent I know does this. They do it out of pride of their child, family, or just because they want to share their life (mostly the good parts) on social media, just like everyone else. It’s just as fake as most other things that go up there, filtered by choice and design, but it leaves a mark for a human being that’s not yet a person, and hasn’t made the choice. That’s a tricky disposition, if you ask me. By all means share, but do it privately, in groups through secure channels.
