As this publishes, I'll be at a training with the folks from Little eLit, learning even more about this topic!
One of the things Devorah Heitner mentioned in her webinar last week was to help parents be aware about the digital footprint they are creating for their young children. Be aware of what you are posting about your children online. What photos? What stories? As soon as they are old enough, ask children for permission to post photos and stories and accomplishments. Be thoughtful about the footprint you are creating for them, and help model for them that thoughtfulness for when they are old enough to create their own.
Related to this, Devorah recommended that parents consider having a documentation-free week. Try going to the playground without taking photos sometime and see what that's like! She's not suggesting giving up documenting those moments altogether, just taking a break from it to see how it changes things.
