- Inspired by Alberto Spada"s Mockimonster drawings, inventive author Saria Tagliaferri has created a new series of early learning board books which deal with basic questions about human life such as appearance and feelings. This book illustrates and explains what teeth are, how they grow, why we have them, how we use them and why they must be looked after properly. Page after page, the Mockimonster illustrations tell the incredible story of a baby"s teeth.
