march of technology may seem unstoppable, but all things digital may have  way to go before they replace  traditional bedtime book -  paper one.  new study shows that paper books are better than e-books for bedtime reading. The study suggests that  good old printed book, with real pages that you turn with your fingers, makes parents and children interact more than they do when reading with  electronic book. Researchers from  University of Michigan studied how 37 pairs of parents and toddlers interacted with e-books and paper books.  researchers found that with electronic books, parents asked their children fewer questions and made fewer comments about  story.
 study involved observing parents and children (aged two or three) reading from three different book formats. These were printed books, basic e-books on  tablet, and enhanced e-books with features such as animation, graphics and sound effects.  researchers discovered that  parents and toddlers interacted with each other less with both types of e-books than they did with  printed books.  researcher said that when they did speak, they were far likelier to talk about  device and the technology rather than about  story. Children were likelier to say things like, "don't push that button" or "don't change  volume" than ask questions or make observations about  story.
