For anyone you know looking to get their child a tablet, this is a great deal. It allows you to declare a Kindle Fire HD a child’s, letting them know the child’s gender and age, and Amazon instantly creates a library of apps, books, and movies that are age appropriate (There’s content here from Disney, Nickeloden, PBS, Marvel, etc.). This way, you don’t have to try out apps first to see if they’re safe. If you have Amazon Prime (which is worth it for the free shipping), it’s $3/month, otherwise it’s $5 (and there are bulk rates).
Yes, it’s one more monthly fee, but if you’re willing to let your kid use (and possible break) your (expensive) tablet, what’s $3 more?
