School's out for summer (or it's about to be), which means the kids are about to be reaching for their screens more often than usual. Swap the tablet or gaming console for screen time you can feel good about with the Kindle Paperwhite Kids. It's packed with kid-friendly books only — no notifications, apps, videos, or other distractions — and it's back on sale for its best-ever price at Amazon.

The Paperwhite Kids is our favorite Kindle for young readers, particularly because it has a waterproof build, unlike the regular Kindle Kids. Kids are unhinged, so a waterproof screen is a necessity. The Paperwhite Kids is also heftier than the adult Kindle Paperwhite, which makes it sturdier and able to withstand just about anything kids throw at it. If anything does manage to break it, however, Amazon will replace it within the first two years.

The newest rendition of the device was released last fall and comes in its thinnest, fastest form yet, as well as a variety of new designs. It features a seven-inch display with a higher contrast ratio and 25 percent faster page turns than its predecessor, which both help to keep kids engaged in the content.

We love that it comes with built-in parental controls and a free six-month subscription to Amazon Kids+, which is loaded with tons of age-appropriate books. That's plenty of time to get them through the lazy summer months. After the six-month trial period, it'll cost $5.99 per month. It's a good thing you'll be saving $40 on the device itself.
