Mattel built a $300 Echo for kids

Before you can knock off for the night. However, there's one thing left to do: read your child a bedtime story. In Mattel's world, you might not have to pick up a book, or even put on voices for their favorite characters. That's because it's working on an Echo-style speaker with an assistant called Aristotle. It's built specifically for kids, offering games, facts and soothing sounds on demand.
