In J.D. Robb's "Innocent in Death," the narrative explores the essence of childhood by emphasizing the importance of curiosity and exploration. The quote, "If children don't push the edges now and again, what's the point of being a child?" suggests that part of being a child is testing boundaries and engaging with the world in a fearless way. This reflects a broader theme about the necessity of growth and learning through experiences.

The assertion underscores the idea that childhood is a unique stage where questioning limits and challenging norms are vital for development. It invites readers to appreciate the value of these experiences in forming identity and understanding one's surroundings, ultimately painting a picture of childhood as a vibrant and critical period in life.
