Vivi & Oki: What’s That Sound? is a gentle story that grows with your child – from listening to first sounds to building simple sentences.

The book supports early communication by focusing on familiar everyday moments and short, simple language.

This is the first book in the Vivi & Oki series, following one calm weekend day – from waking up, going out, playing, to eating, bathing, and settling down to sleep.

For pre-verbal children, the focus is on the sounds they hear and begin to copy.
For older toddlers, it introduces simple sentences rooted in relatable, day-to-day situations.

Designed for babies and toddlers aged 6 months–3 years.
