Vivi & Oki: What’s that sound is a gentle picture book for babies and toddlers (6 months–3 years) that supports early communication through everyday sounds and short, clear sentences.

The story follows one familiar weekend day – from waking up, going to the bakery, the beach, lunch in the park, playground time, helping at home, cooking, eating, bath time, and bedtime.

Designed for shared reading, the book encourages listening, repetition, and early word-building in a calm, pressure-free way. Its sturdy board book format and handy size make it easy to take anywhere, while colorful illustrations spark curiosity without overstimulation.

Perfect for family reading, therapy sessions, early literacy collections, or early learning settings.
