We often hear about the benefits of reading storybooks at bedtime for promoting vocabulary, early literacy skills, and a good relationship with your child. But the experts haven’t been in your home, and your child requests the same book every single night, sometimes multiple times a night. You both know all the words off by heart.
Given activities occurring just before sleep are particularly well-remembered by young children, you might wonder if all this repetition is beneficial. The answer is yes. Your child is showing they enjoy this story, but also that they are still learning from the pictures, words, and the interactions you have as you read this book together.
Kids want repetition
A preference for familiarity, rather than novelty, is commonly reported at young ages, and reflects an early stage in the learning process. For example, young infants prefer faces that are the same gender and ethnicity as their caregiver.
But even three-day olds prefer looking at a novel face if they’re repeatedly shown a picture of their mother’s face. So once infants have encoded enough information about an image, they’re ready to move on to new experiences.
Your child’s age affects the rate at which they will learn and remember information from your shared book-reading. Two key principles of memory development are that younger children require longer to encode information than older children, and they forget faster.
