As parents, we dream of giving our children the best possible future. But what kind of world will they inherit? Teaching sustainable practices to young children isn't just about protecting the environment—it's about nurturing empathy, responsibility, and a deep connection to the world around them. The beautiful thing about early childhood development is that children are naturally curious about nature and eager to help. When we harness this innate wonder through a child-centered approach, we're not just teaching habits; we're shaping values that will last a lifetime.
At Runningbrook International Preschool, we've witnessed firsthand how children as young as six months begin to notice the natural world—the flutter of a butterfly, the texture of leaves, the sound of rain. These moments of discovery are the foundation for environmental awareness. Through play-based learning and gentle guidance, even our youngest learners can begin to understand their connection to nature and their role in caring for our planet.
In this article, we'll explore what sustainable behaviors look like at different developmental stages and share practical strategies you can implement at home. Remember, you know your child best, and every small step toward sustainability matters.
Children develop environmental awareness gradually, and what sustainability looks like will vary depending on your child's age and developmental stage. Here's what you might observe:
At this stage, children are sensory explorers. You might notice your little one:
These early experiences form the foundation for later environmental understanding. Research from the North American Association for Environmental Education suggests that positive nature experiences in the first years of life create lasting connections to the natural world.
During this period, children begin to understand cause and effect and can follow simple routines. You might observe:
Older preschoolers can grasp more abstract concepts and take on greater responsibility. You might see:
It's important to remember that children develop at different rates, and your child may show interest in some areas before others. This is completely normal. The goal isn't perfection—it's progress and positive associations with caring for our world.
The wonderful news is that teaching sustainability doesn't require special equipment or extensive knowledge. It's about weaving eco-conscious practices into your daily life in ways that feel natural and even fun. Here are five strategies that align with a child-centered approach to learning:
The foundation of environmental care is connection. Children protect what they love, and they love what they know. Even in a busy city like Santiago, opportunities for nature connection abound.
Try this:
At Runningbrook, our extensive outdoor play spaces allow children to develop this connection daily. We've seen how children who spend regular time in nature develop not just environmental awareness but also improved focus, creativity, and emotional regulation.
Young children learn primarily through observation and imitation. When you make sustainable choices and explain them in simple terms, you're providing powerful lessons.
Try this:
Research in early childhood development confirms that children are remarkably attuned to adult behaviors and attitudes. When we model sustainable practices with genuine conviction, children absorb both the action and the value behind it.
Sustainability works best when it becomes automatic. Establishing routines makes eco-friendly behaviors feel normal rather than burdensome.
Try this:
Consistency is key. It may take several weeks for a new routine to become habit, so be patient with yourself and your child. Celebrate small victories along the way.
Play is the language of childhood, and sustainability concepts are perfect for playful exploration. Through play-based learning, children can experiment with environmental ideas without pressure or judgment.
Try this:
At Runningbrook, our play-based learning approach means that sustainability is woven into daily activities rather than taught as separate lessons. Children in our multicultural environment share different perspectives on how their families care for the earth, enriching everyone's understanding.
It's tempting to explain environmental issues by focusing on problems, but young children aren't developmentally ready to process climate anxiety or environmental disasters. Instead, focus on gratitude and wonder.
Try this:
This approach aligns with expert consensus in early childhood education: young children thrive when learning is rooted in positive emotions rather than fear.
One of the beautiful aspects of teaching sustainability in a multicultural environment is the opportunity to learn from diverse traditions. Different cultures have rich histories of sustainable practices—from indigenous wisdom about living in harmony with nature to traditional food preservation methods that reduce waste.
At Runningbrook, with families from over 35 countries, we celebrate this diversity. You might explore your own family's cultural heritage for sustainable practices to share with your child. Perhaps your grandparents grew their own vegetables, mended clothing rather than replacing it, or had special ways of conserving resources. These stories connect sustainability to family identity and make it feel personally meaningful.
Additionally, bilingual education offers unique advantages in environmental learning. Research suggests that multilingual children often show enhanced cognitive flexibility, which can translate to creative problem-solving—a crucial skill for addressing environmental challenges.
At Runningbrook International Preschool, sustainability is integrated into our child-centered approach across all age groups. Our extensive outdoor play spaces provide daily opportunities for nature connection, while our small group sizes allow educators to follow each child's emerging environmental interests.
In our Growing Steps program (6 months to 2 years), babies and toddlers explore natural materials through sensory play. In Playgroup and Kid's Club (2-4 years), children participate in simple gardening projects and learn basic recycling routines. Our Pre-Kinder students (4-6 years) take on more complex projects, like composting and planning gardens, developing both environmental knowledge and leadership skills.
Our dedicated educators model sustainable practices throughout the day, creating a consistent message between home and school. When families and educators partner together, children receive reinforcement that helps sustainable habits truly take root.
Teaching sustainability to preschoolers isn't about achieving perfection or transforming your lifestyle overnight. It's about taking small, consistent steps that nurture your child's natural connection to the world around them. Every time you marvel at a butterfly together, every recycled bottle, every plant watered with care—these moments add up.
Remember, you are the expert on your own child. You know what approaches will resonate with their unique personality, interests, and developmental stage. Trust your instincts, be patient with the process, and give yourself grace when sustainable choices feel difficult.
The most important thing you can do is to approach this journey with joy. Children who associate environmental care with positive emotions—wonder, gratitude, accomplishment, connection—will carry these values forward throughout their lives. Together, we're not just teaching habits; we're raising the generation that will shape our planet's future.
At Runningbrook, we're honored to be part of this journey with you. Since 1993, we've been nurturing curious, confident, and caring children, and we believe that together—families and educators working as partners—we can grow green hearts that will make a difference for generations to come.
