The oyster, in order to protect itself from any unwanted visitor that invades its "home," covers the foreign body with a fine substance, the nacre, and thus gradually creates the pearl. The story of the little otter highlights a common fear among children, that of being separated from the maternal embrace. However, there is a way to transform this fear into a "can" that leads the child to discover their own treasure. To ensure that children have a healthy social life based on effective relationships, they must cultivate empathy, the ability to put themselves in others' shoes. This need is addressed by the illustrated books in this series, which promote emotional intelligence. The series "Books that Promote Emotional Intelligence" consists of 22 books.
