Frequently Asked Questions
What is the age range for the sound books?

Our sound books are perfect for ages 0-5 years old. With our sound books, children can benefit from listening to nursery rhymes, getting an introduction to reading, and enjoying bonding time with their caregivers from a very early age. Our recordable books are great for ages 3-10. Toddlers can push the button and listen to the stories, while older children can begin to read using the highlighted words to help word recognition. Young readers can even read and record their own voice! Find all our customers favorite books and collections

For the love of books

Hi, I'm Cali! I've loved books since childhood and wished to share this enthusiasm with my children.

I'm French of Caribbean origin (Martinique, to be precise!) and grew up in Paris — but I now call Los Angeles home, where I live with my two young children. My passion for books stems from the musical board books I found in France. They had embedded sound buttons that babies and children pushed to hear songs and musical tunes. I wanted to offer the same pleasure to children in the English-speaking world. Thus, Cali's Books was born.
