Some of the points, on this list, seem like no duh parenting moments; other points come across as alarmist. But, I did find a few things helpful, like this:
Teach kids that when someone offers to show them anything on a screen, they should ask “What is it?” before looking.
And this regarding streaming services:
Many will tell you to just set up a separate profile for the kids–easy! But that’s not enough. The profiles are not password protected and kids can easily switch profiles. Your best line of defense is to set up parental controls. Some parents find it annoying that they have to enter a password so that they themselves can watch content, but it’s a small price to pay to protect your child from mature content!

I have to admit, I always thought that having separate profiles would be enough. Setting up a PIN, for all accounts, to help govern content watched, seems smart.
