In addition to this advice we would encourage families to have video games and screens used in shared family areas so you can see what kids are doing. This also means they can talk to you more easily about anything that upsets them.
In Roblox, selecting the Restricted setting for your child’s accounts ensures they can only access games that have been checked for appropriateness.
On Youtube select restricted mode so that children cannot access content flagged by the YouTube community as potentially sensitive.
In the event of your child feeling vunerable or distressed by seeing inappropriate material online, there are a number of organisations that can offer direct support to you and your child.
