I think it’s essential for children to try out new behaviour in a safe place. Like it or not, this probably means at home, on you, the parent. It’s a child’s way of spreading their wings; trying out new personalities and traits. A safe way to experiment is important because your child knows that you will always love her or him no matter what. But a book can also be a safe way to try out new behavior as a reader if you talk about the book in the context of how it makes you both feel.
