A parent should reach for this book when their young child is beginning to assert their independence, perhaps by saying "I do it!" or expressing a desire to explore on their own. This gentle, repetitive story follows a little mouse who decides to leave home. When his family asks where he is going and what he will do, his simple, honest answer is always, "I don't know." This book beautifully validates a child's need for self-discovery without needing a plan or a reason. It reassures children that their curiosity is valid and that they will always have a loving home to return to. Its simplicity and soothing rhythm make it perfect for preschoolers wrestling with the big feelings of growing up.
The core theme is the developmental separation between parent and child. The approach is entirely metaphorical and gentle. The resolution is deeply hopeful, reinforcing the concept of a secure family base from which a child can explore and to which they can always return. There is no ambiguity or lingering sadness.

Sign in to write a reviewThis book is perfect for a 3 or 4-year-old who is in the early stages of individuation. They might be pushing boundaries, saying "no" more often, or expressing a desire for autonomy. It's also for the introspective child who may not have words for their feelings but feels a pull toward their own experiences, separate from their family.
No preparation is needed. The book's strength is its simplicity and can be read cold. Parents should be prepared to embrace the repetition, as it is key to the book's comforting message. A parent could think beforehand about how they react to their child's own "I don't know" moments. A parent might pick up this book after their toddler packs a small toy in a bag and declares they are "running away" to the backyard. Or perhaps their preschooler is constantly responding to questions with a frustrating "I don't know," and the parent needs a way to reframe this phase as a healthy part of development rather than defiance.
A 3-year-old will connect with the repetitive text, the animal characters, and the basic concept of leaving and coming home. A 5-year-old will begin to grasp the deeper emotional layer: the validity of wanting to do something without a clear goal, and the quiet confidence it takes to follow one's own curiosity.
Unlike most books about adventure, this one celebrates the journey without a destination. Its unique power lies in validating the state of "not knowing." It tells children that it's okay to explore out of pure curiosity, without a plan or an answer for worried adults. The minimalist text and gentle illustrations place the focus entirely on this quiet, profound emotional truth.
A little mouse announces he is leaving home. His mother, father, sister, and brother each ask him, "Where are you going, little mouse?" and "What are you going to do?" To every question, he simply replies, "I don't know." Despite their worries and suggestions for things he could do at home, he ventures out. After a brief, quiet moment of exploration, he returns home to a warm and loving welcome from his family.
