There is a version of YouTube specifically made for children, called YouTube Kids. It creates a safer environment for children to watch videos and gives them the freedom to make their own choices as to which videos they would like to watch.

How to create a YouTube Kids account:

Open the YouTube Kids app and follow the on-screen instructions.

When you're asked to, enter the year that you were born.

Choose whether or not to sign in to the app to get greater access to features and parental controls.

If you already have an account on your device and want to sign in with that account, select it and tap Sign in. If you do not yet have a Google Account, add or create one by following the prompts. After you add your account, tap Sign in.

Read the YouTube Kids parental consent info. If you agree, tap Done and enter your password.

Set up a profile for your child. YouTube will try to customise the app for your child's age. When you enter a month of birth, the app will use this to more accurately provide an age-appropriate experience. Only you and your child can view this info.

Select one of the following content experiences for your child:

Preschool (Ages 4 and under)
Younger (Ages 5–8)
Older (Ages 9–12)
Approve content yourself

The Preschool content setting (ages four and under) allows children to watch videos that promote creativity, playfulness, learning and exploration. Search results in Preschool are limited to content recommended for children aged four and under.

The Younger content setting (ages 5–8) allows children to search and explore songs, cartoons, crafts and more. With this setting, search results will be limited to content for children aged eight and under.

The Older content setting (ages 9–12) allows children to search and explore extra music videos, gaming, science and more.

With Approve content yourself, your child can only watch videos, channels or collections that you've approved. Collections are videos and channels grouped by topics, such as science and music. With this setting, your child will not be able to use the search bar tool.

You'll now take a parent feature tour of the YouTube Kids app. The tour highlights where to find parental control settings and how to block and report videos.

Your child can now use YouTube Kids. Select the profile of the child using the app to get started. You can return to Settings at any time to change your parental control options.

Youtube’s built-in timer allows parents to limit screen time by telling kids when it's time to stop watching. The timer will display a friendly alert and stop the app when the session is over so that you don't have to.

Here's how to set the timer:

Tap the lock icon in the bottom corner of any page in the app.

Read and enter the numbers that appear, or enter your custom passcode.

Select Timer.

Use the slider bar to set a time limit.

Tap Start Timer.

Children will see a "Time's up!" notification and the app will be locked once the time limit is reached.

To unlock the screen:

Tap the lock icon in the bottom corner of any page in the app.

Read and enter the numbers that appear, or enter your custom passcode.

Select Timer and then tap End Timer.
