Obviously, I would say have lots of conversations with your children about what it means to be responsible when using the Internet, and with that comes stages of responsibility. A lot of parents just give their kid a phone and then they have access to everything. Instead of doing that, start off with very limited access and then talk about being a responsible digital citizen, and continue those conversations and check. A lot of parents just can't keep up with all the apps and everything out there.
I think we need some education and some workshops for parents, for people to share what is out there and what they need to be aware of, because it's hard for parents to stay educated in that way.
