At Clavis, our focus is on what's best for children. We believe that books play an important role in each new phase in life. Our toddler books are tailored for every stage from 0 to 3 and focus on the five most important themes in their life: daily life, skills, emotions, the world, and language development. The age range and theme of every book in our toddler series can be found on the back cover in the form of a colored train.
