Bright and sunny characters, expressive faces, and attractive art catches the young child's eye. Awareness building about themselves and others is really key in these toddler and preschool aged books. Common themes of sharing, self-esteem, reverence for the natural world, feeling alone or loved, and making the world a better place are great topics for young children and beyond. Reading, reviewing, and reflecting with preschoolers about these topics is a great start for these themes to be introduced to them. Using these rhyming books for discussion and pointing out real world examples will further deepen the understanding of these lessons in life. Great books! My 3-year-old loves them.
