A simple, interactive portrait of a young mouse boy and his daddy forging a now-and-forever bond through sports and activities. Someday Charlie will be big and brave--just like his daddy! From climbing up the slide to climbing a mountain, a boy looks to his dad for what he can do now, and what they'll someday do together. Celebrates the role physical activity plays in parent-child relationships and how it can lead to lifelong connections. Gatefolds reveal the daddy-equivalent of the boy's activities, and how they'll share activity-based adventures when the boy becomes bigger (and braver!).
