I barely use Facebook (only to look around, mostly for family stuff).I don't use facebook that often as far as sharing things (never pics of kiddo) so I'm no expert, but can't you set your privacy setting so that only friends can see those kinds of posts?
I mean if you have it set to public and post a picture of sensitive material then the world can see it, but if you have it on lockdown wouldn't only your friends have permission to view it?
But, I've heard that FB has changed rules and made public things that people had set to private. It was private when they put it on FB. Then suddenly a year later, rules/settings change.
Please, someone correct me if I'm wrong.
