You can't always control what your kids are watching on all those screens, but you can set boundaries.
Start by setting up a separate profile for your child on Netflix.
You'll need to log in to your account online, then go to you account and select Manage Profiles.
Now add profile and check the box on the right.
Or just put your entire account on lockdown.
Go to Account and click on Parental controls.
Type in your account password first, and now create a four digit pin and select the protection level.
You'll have to type in the passcode to play content rated above the age range you selected.
YouTube has a kids friendly app with tons of videos for your little one.
The app requires an adult to sign up and set viewing restrictions.
But it's not always fool proof.
So it's best to take precautions.
First make sure only you can change the settings.
Tap the lock icon, click on set my own password, and follow the instructions.
If you see a video you don't approve of, click on these three dots and block the video, or the entire channel to prevent from playing in the future.
