Parents need to know that YouTube Kids is a kid-targeted portal to YouTube aimed at kids from preschoolers to tweens that features curated, ad-supported TV shows, music, educational videos, and user-created content. As of 2019, there's also a YouTube Kids website. It's worth noting that since there are regular updates, the channels and videos are always subject to change. The app has drawn lots of public scrutiny and controversy for including some clearly inappropriate videos and ads (with nudity, alcohol, and profanity), as well as fast-food and junk food ads that push unhealthy food (some of which look a lot more like entertainment than advertising, making it hard for kids to know they're being marketed to). If parents sign up for a YouTube Premium subscription, there are no ads, and kids can watch offline. Families can also access it via television, depending on their device. To access the full set of filters, parents will need to sign in using a Google account.
