As someone who loved reading books growing up, I believe that books are essential and very useful in many ways. While I do agree that serious educational books are great because the main purpose of the book itself is for educational purposes, I believe people, in this particular context, children, can also get new knowledge from reading entertainment books. Besides, even if one reads any books that do not serve educational purposes as a main goal, I do not think it is a way of wasting someone's time as long as the book is suitable for one's age, understanding, and mental condition. Reading, in fact, is a great way to spend time, especially for children, and it would be even greater if they could find a source of entertainment through books.
