One of the first books I read on children and creating a digital profile was Born Digital by John Palfrey& Urs Gasser. The book kicked started my thinking about how children relate to and utilize the internet. I would recommend reading the book or at least checking out their website, youthandmedia.org. Here, the authors have posted many videos inspired by their book.
My kids had no interest in the book or me talking about the book, but they liked the videos. I have posted a few my kids found most interesting.
1. Start talking about online information and digital profiles by watching this video with your kids.
2. Remember the Star Wars kid? I did but my kids had no idea. Great introduction to privacy and the downside to being the subject of a viral video
