YouTube is a platform for user-generated content—anyone can create and post content. The company does its best to filter content, but it’s not perfect. There may also be commercials that aren’t appropriate for children.
You can improve your YouTube experience by subscribing to reputable channels. And if you sign up for YouTube Premium, you won’t see any ads and will have access to exclusive content.
But the safest way for kids to consume content is with a responsible adult who can manage the experience and discuss the videos with them.
