A timeline in children's book terms refers to a visual tool that highlights key events in the life of a book from concept to publication. This may include milestones such as the initial idea, drafting, editing stages, illustrations, and the launch date. Timelines can be essential for both authors and publishers to track progress, plan deadlines, and ensure that the project stays on schedule. In educational contexts, timelines can also help children understand the sequential nature of storytelling and character development within the narrative.
