Put Them in
Charge of Their Library

Give your child some independence in their library. Allow them to organize it how they would like (while still maintaining order, of course). Help them decorate the space or arrange the books the way they want to. After you're all done, let them know that it's their job to keep the books in order and their library looking nice.
Encouraging children to maintain their library on their own asks them to practice responsibility. It will help them learn not only how important it is to look after your own space, but also how valuable and special books are. .
