From rentals at Redbox and the internet, to movies on Blu-ray and DVD, and even trips to the theater, entertainment should be earned. Some parents have taken the step of charging their children 50 cents to watch a TV show or movie at home. That sounds extreme, but it certainly helps the kids understand that entertainment is a treat. Books, on the other hand, should always be free to your kids. If they know it's going to cost money to watch that cartoon or TV show, the prospect of a free book looks way more enticing.
