Terms such as happiness, health, and harmony are often used in early childhood education in ways that risk becoming vague or idealized. In this article, I do not approach these concepts as goals to be achieved or states to be maintained, but as lived experiences that emerge through everyday practice. I use the term Three H’s—Happiness, Health, and Harmony—not as a formal framework, but as a practical lens to explore how outdoor opportunities can support children’s and educators’ well-being while aligning naturally with curriculum and daily life.

When I refer to happiness in early childhood, I do not mean constant joy or uninterrupted positivity. Contemporary early childhood curricula emphasize play-based learning, and at the heart of play is children’s sense of enjoyment, freedom, and engagement. Happiness, in this sense, is about children feeling safe, having opportunities to make choices, experiencing a sense of autonomy, and feeling comfortable expressing their emotions, including joy, curiosity, frustration, and uncertainty. Children do not need to be happy all the time; instead, they need environments in which they can feel secure, heard, and free to engage in experiences that are meaningful to them. Framing happiness in this way shifts the focus from keeping children constantly cheerful to supporting their overall well-being and emotional safety.
