Create your account then your kid’s account.
The first step is setting up a main user account. Since you’re the parent, that’ll be yours. The process is painless and can be done on your PlayStation 5 when you initially start up the system. Don’t let your child play on the main account, though. If they do, and get far in a game, you won’t be able to move their progress over to their new account.
Once you’ve got your own account set up, you’ll want to download the PlayStation app for your smartphone.
Log into your account and tap the Settings button in the top right corner of the screen.
Scroll down to the PlayStation Network settings and select Family Management.
