Step-by-step explanation:
Caldecott books are most appropriate for children ages 2.5 to 6. This age range aligns well with the target audience for picture books that are typically honored by the Caldecott Medal, known for celebrating distinguished American picture books for children.
The content and illustrative quality of these books are designed to engage children in this age group, fostering early literacy, creativity, and a love for reading through visually appealing and narrative-rich content. However, Caldecott books can be enjoyed by people of all ages for their artistry and storytelling, including childless adults or the elderly.
