The dog goes woof, woof, the duck quacks, quack, and the car goes beep, beep. In baby's first sound book, little early readers bring to life the brightly colored, cheerful, and high-contrast images from their familiar surroundings – all with a simple press of a button. The onomatopoeic words are fun for the baby, promote important early parent-child communication, and subtly support the child's language development.
