Choose strict privacy settings, and check them regularly, since privacy policies change often. And limit your audience further by using each program’s tools to direct your post to the right people, Knorr says. (For example, create a family subgroup on Facebook for sharing baby pictures.) “It doesn’t mean that post is never going to get out, but makes it more secure,” she says. Kids should have private accounts that can’t be found by searching for their names.
