1. You have multiple copies of the same book.
2. The book is falling apart.
3. Your child has outgrown the book (too youthful for their age).
4. You or your child didn’t like the story (too scary; it’s inappropriate, doesn't make sense, etc.).
5. Because the space that you have to store the kid's books has reached capacity (note: you have to have decided how much space works for you ahead of time!).
