YouTube Kids, the family-friendly version of YouTube with built-in parental controls and a curated selection of kids content, is now available on Amazon’s Fire TV. The app’s arrival comes after Google and Amazon came to a mutually beneficial agreement that also allowed YouTube to launch on Fire TV last year and Amazon’s Prime Video to make its way to Chromecast and Android TV.

The agreement was meant to soon see the additions of other YouTube apps, including YouTube TV and YouTube Kids, on the Fire TV platform. But while YouTube TV arrived on Fire TV last September, YouTube Kids has seen a significant delay, considering it was promised to arrive sometime in 2019.
