I have a lot of things in common with the author of this article, Erin Barton. We both have 3 young children; they all have access to digital devices; my 8 year old thinks she is twice as old as she is; and we have already started having the conversation about safety and privacy on digital devices.
The simple solution would be to keep them off the devices until they are older, but there are so many educational opportunities for them (and, I can’t deny that they are best and cheapest babysitter going).
Inevitably, our kids will have their own devices and will be free to do whatever it is they want to do on social media. I shudder at the thought but teaching them at a young age to be responsible and safe will give them the tools to make good decisions later.
