Here's why:
* Children's: The book is written in a simple and engaging style that is appropriate for young readers. It focuses on themes of family, adventure, and everyday life, which are common interests for children.
* Historical Fiction: The story is set in the 1870s in Wisconsin, and it accurately portrays the life and culture of a pioneer family during that period.
* Fiction: While the story is based on Laura Ingalls Wilder's childhood experiences, it is a fictionalized account. Some events are exaggerated or embellished for storytelling purposes.
So, although the book is based on real events, its focus on children and its fictionalized elements make it fall firmly into the children's historical fiction genre.
