My wife and I recently had our first child, and we decided we didn't want her to have any kind of social media presence until she was old enough to make that decision for herself. It's been a challenge ensuring friends and family don't post stuff about our daughter, but reading this reinforces that we're making the right choice.
What is "old enough"?
