To encourage your child to read, have plenty of children's books available. In addition to buying books, try to arrange a regular monthly trip to the local library.
Once you know your child's interests, select related books. Also choose a few other books that your children may be interested in to expand their interests. If you need suggestions, speak to the librarian in the children's section of your library. When in the bookstore, ask the sales people in the children's area for popular authors and titles. If your children are in school, the teacher can also give you suggestions of popular children's books. Always mix fiction and nonfiction. In order to further encourage reading, take time to read books together.
