Amazon has launched its child-friendly Kindle FreeTime Unlimited service, which is designed to help parents control the content their children can access on their tablets, without the fear of running up huge bills.

The service provides free access to thousands of books, apps, movies, and TV shows and is geared toward children aged between three to eight.

The retailer is marketing it as an "all-you-can-eat content service" for kids for the Kindle Fire and Kindle Fire HD devices.

"As a parent it's hard to predict what my daughter is going to enjoy, or which movie she's going to watch 50 times in a row-so I buy a range of content and hope for the best-but I get it wrong frequently," said Peter Larsen, Vice President, Amazon Kindle. "FreeTime Unlimited gives kids the freedom to explore age-appropriate content on their own and pick for themselves what they want to watch, play or read next. For as little as $2.99 a month, your child will have unlimited access to thousands of popular books, games, educational apps, movies and TV shows from Disney, Nickelodeon, Houghton Mifflin Harcourt, PBS, Sesame Workshop and more."

The $2.99 price is for people who already pay $79 a year for Amazon's Prime content streaming service. Those without Prime will have to pay $4.99 per child or $9.99 for the family.

Amazon avers that FreeTime Unlimited gives kids access to all of their favorite characters, such as Elmo, Dora, Thomas & Friends, Cinderella, Buzz Lightyear, Lightning McQueen, Curious George, and more.

Every child can create individual profiles on their own FreeTime Unlimited account, giving them their own library and home screen and allowing them to save their place in a movie or TV show when someone else picks up the Kindle Fire.

Additionally, Amazon has removed all advertisements, payments and social media from their apps and made sure everything offered is included in the subscription price. The service includes partnerships with the likes of Disney, Nickelodeon, HIT Entertainment and PBS, bringing video, audio, eBook, and app content from all these providers.

"With games like Where's My Water? and Where's My Perry? Disney is bringing hours of entertainment to Kindle users in any age group," said Tim O'Brien, VP of Business Development at Disney Games.

Kindle owners can sign up to FreeTime Unlimited on the company's Web site.
