Sound books complement you reading books out to your children, by adding an auditory input. Besides improving the child’s listening skills and attention span, these books build a relationship between the written and spoken word in the child’s mind, which helps in building language skills. Sound books are a great way to let your child explore how things look, as well as how they sound, all by themselves. These books also improve their pronunciation and listening skills in the process. As a bonus, these books are very engaging and a great way to keep little kids occupied in a constructive way.
