Parents and toddlers who read paper books together speak and interact more when compared with those who read e-books，researchers foun D.Reading with a child is a hugely important developmental activity as it helps youngsters learn new words, broadens their knowledge and provides time to bond with loved ones. So scientists wanted to see if parents and children acted differently when they read books together using traditional media versus electronic devices like tablets.To investigate, the researchers found 37 pairs of parents and healthy toddlers between two and three years ol D. They asked them to read from three different types of media: enhanced electronic books with sound effects or animation, a basic electronic book, and a print book's Researchers found parents and toddlers spoke more when interacting with a paper book rather than a story on an electronic tablet. What's more, parents used richer language when using print books compared with tablets, and collaborated more with their children. But parents were less responsive and children were less engaged with their parents when reading e-books, said Dr. Tiffany Munzer, corresponding author of the study at the University of Michigan C.S. Mott Children's Hospital. The findings were published in the journal Pediatrics.Munzer pointed out. however, that the study was limited in several ways, including that the team did not test the toddlers reading comprehension. It was also limited by the small sample size, and the fact that the team used only one commercially-available app for the e-books." That isn't to say there is no benefit to electronic book reading compared with doing nothing. Just less compared with print books. Print books are just better for promoting rich language from their parents and more conversations between parents and children, said Munzer.Munzer said that parents always know their children best, "so they should feel empowered to adjust the reading experience to what they know their children are
