Stop putting your children on Facebook, Instagram, Twitter and any other social network that you might use.
Your kids are growing up to already have a bunch of information about them online. Who knows what could happen to those pictures, videos and comments? Will they come back to haunt them when they want to be President? What about when they want to be an engineer and they need a specific security clearance in order to work?
What if someone uses your child's photo to steal money from other people?
Think about what you put online. You have no idea who will use it for what.
