An advantage of buying a children’s book rather than borrowing it from the library is the opportunity to read it to the child repeatedly over an extended period of time.
How is repeat reading of a kid’s book of benefit to an infant, toddler, preschooler, or kindergartner? There are probably at least three ways in which repetition is beneficial.
First, if a child likes a certain book, he or she will certainly take pleasure in hearing it read more than once, and in fact may enjoy it even more during repeat readings because of the deepened understanding that comes with repeat readings.
Second, since a child will often continue to pick up on various nuances, whether verbal or visual, with each repeat reading, this ongoing freshness will not only enhance the child’s enjoyment of the specific book, as mentioned above, but will also bolster his or her appreciation of the masterful nature of the story and illustration elements in great books in general, and may also help develop and sharpen the child’s mental and visual acuity as he or she learns how to absorb all that a well written and illustrated children’s book has to offer.
Third, children derive comfort and a sense of security from things that are familiar and things that are part of routines. Reading books at regular times, such as at bedtime, can serve as a comforting routine, and repeat reading of familiar books even more so. When a book, including its story, characters, and illustrations, becomes familiar to a kid, he or she may cherish its company much like a beloved blanket or teddy bear.
So, repeat reading of books to a child has clear and important benefits. That’s not to say that new books are less beneficial. Ideally a child should be read a combination of new and old books on a regular basis.
