You can use parental controls for children of any age if it feels appropriate. If your child is under the age of 5, you may prefer to sit with them and monitor their internet usage that way. As your children grow and begin to use devices without supervision, it’s a good idea to turn on parental controls. Between the ages of six and 10, children begin using apps that you may wish to monitor, and by the time they reach secondary school, most children begin exploring social media apps, which can pose significant risks without parental controls.
