"We're trying to use social media education for them as well ... so they know about permanence and about being very responsible with every image that you put up."

The lives of modern parents are more complicated by having to add social media training to the list of things we need to do to keep our children safe, Feliciano said.
So what's a parent to do?
Magid, the Internet safety expert, said parents should check their privacy settings for any online service they use to make sure something they only want to share with friends is not being seen by the general public. He also said parents need to keep reiterating one message to their kids: "Not to put anything online that you wouldn't want your grandmother or future love interest or future employer (or a future college administrator) to know."
But beyond that, he said parents can't really rely on themselves, software companies or even the government to keep children safe online.
For instance, a new California law went into effect last week, the first law of its kind in the nation, that will allow kids under 18 to have the power to delete something they posted.
The problem, said Magid and other parents, is that if someone shares something your child posted that your child now wants to delete, your kid is out of luck. Also, the new law doesn't protect childlren from any photos or posts that their friends or enemies post about them.
"The danger is not even so much what you've taken and shown the world, but it's what other people have tagged you in or stupid things you did (and) you didn't even know anyone had a camera," Rowley said. "So it really comes down to parents. We really have to teach morals, ethics, how to live your life with integrity."
Emily, the mom and blogger from North Carolina, put it another way.
"You have to parent online," she said. "You have to sit down with your kids and explain what they're getting into."
