YouTube doesn't talk very much about what it has to offer for younger audiences, but through its Kids app, parents have easy access to a great library of child-friendly material. Not long ago, the app introduced a "reading" category built around the theme of books and literary characters. Regular updates to the app are also occasionally introducing new features. The latest update includes a few hints about some improvements that may be coming soon, including more control over offline videos and profiles for easily swapping content for different kids.
