This chapter examines Future Fluency as the fifth dimension of the Quantum Child Framework. I address how children can be prepared to imagine, design, and engage with futures that are uncertain and rapidly evolving. The chapter explores the psychological dynamics of anticipation, showing how children move between hope, fear, and creativity when thinking about tomorrow. Case studies illustrate common patterns of future readiness, from anxiety about technological change to playful experimentation with possible worlds. Developmental stages highlight how imagination functions as foresight in early childhood, how pre-adolescents grapple with wonder and worry, and how adolescents begin to engage with futures as spaces of possibility. Practical strategies are offered to help families cultivate future fluency, including narrative practices, scenario play, and rituals that anchor imagination in everyday life. I conclude by framing future fluency not as prediction but as preparation: equipping children to live with ambiguity, to envision alternatives, and to contribute actively to shaping the world they will inherit.
