This year, I had the amazing opportunity to attend the 30th International Montessori Congress held in Merida, Yucatán. This event, happening every few years, is an opportunity for Montessorians throughout the world to come together to reflect and discuss the important work of educating the whole child. This year’s theme was, Joyful Journey, “a global celebration of growth, learning, and connection inspired by Montessori education.” Over the course of four days, we listened to Montessori trainers, psychologists, and other experts in the field of human development as they shared with us their research, observations and knowledge. Among the featured speakers were Dr. Adele Diamond, a leader in developmental cognitive neuroscience; Dr. Angeline Stoll Lillard, author of Montessori: The Science Behind the Genius and director of the early development Laboratory and the Montessori Science Program at the University of Virginia; and keynote speaker, Dr. Gabor Mate whose work focuses on addiction, trauma, childhood development, and the relationship of stress and illness. The Congress opened with Dr. Maté's keynote address on the needs of the child and what he described as the "biology of loss." He spoke about the essential developmental needs of every child: secure attachment, emotionally attuned relationships, the freedom to experience emotions—including grief, sadness, fear, and joy—opportunities for unstructured play in nature, and the presence of calm, consistently available caregivers. Rather than focusing only on overt trauma, Dr. Maté explored what happens when even one of these fundamental needs is not fully met. He explained how chronic stress or emotional misattunement can influence a child's developing brain, affecting both physical health and behavior. His message challenged us to reconsider the purpose of education. If our goal is to help children become self-regulated, compassionate, and independent thinkers, then our work must extend beyond academics. How do we, as educators and parents, support that development? Dr. Maté's answer was both profound and beautifully simple: we build relationships. He argued that the single greatest influence on a child's brain development is the quality of the relationship between the child and their caregiver. The message of relationship was echoed throughout the conference and across multiple speakers. Strong, supportive relationships foster resilience, help children understand and regulate their emotions, encourage healthy vulnerability, and cultivate trust. While I came away with countless new ideas and insights, this was the lesson that resonated with me most deeply as both a teacher and a parent. On the surface, we all recognize the importance of connecting with children. But when we pause to consider the profound influence we have, not only on their daily experiences but on the architecture of their developing brains and the people they are becoming, we are reminded that our greatest work is not simply teaching lessons. It is building authentic relationships, being fully present, and offering each child the unconditional respect, care, and love they need to flourish. The Congress served as a powerful reminder that Montessori education is not simply a method of teaching; it is a way of honoring the humanity of every child. As I return to the classroom, I do so with renewed purpose and gratitude, committed to nurturing not only my students' minds but also their hearts, knowing that the relationships we cultivate today will shape the adults they become tomorrow.
