If you’re buying your kid(s) a Kindle tablet this Christmas, then it may be worth checking out Kindle FreeTime, a new, “all-you-can-eat” subscription service from Amazon that’s designed specifically for those aged between three and eight. It provides unlimited access to apps, books, games, movies, and TV shows that are all curated for “age-appropriateness,” with content from the likes of DC Comics, Disney, Marvel, Nickelodeon, and more.
