answer:None. I wouldn’t have forced any book on a child unless I wanted to make him hate it. I did lots of reading aloud to my kids when they were young. By the time he was six, my older son was an extremely capable and enthusiastic reader (read the entire Oz and Narnia series by the time he was seven). He grew up to become a philosophy major and later attended law school, so reading has been a major aspect of his life. My younger son, in the same environment, with thousands of books on hand and three readers in the family, never developed the habit at all. I really don’t know what explains the difference, but it wasn’t because I bullied either one.
