How do I teach my preschooler where food comes from and why it matters?

Start a windowsill herb garden or grow cherry tomatoes together — watching seeds become food is magical for preschoolers. Visit farmers' markets and let them pick out produce. Talk simply about the journey: 'This carrot grew in the ground!' Explain that bees help flowers grow and worms help soil stay healthy. Composting kitchen scraps is a hands-on way to teach the cycle of nature. At this age, the goal is wonder and connection to nature, not environmental worry. Discuss nutrition and nature exposure with your pediatrician.
