In the first three years of life, the foundations of physical and also of psychic health are laid. In these years, the child not only increases in size but passes through great transformations. This is the age in which language and movement develop. The child must be safeguarded in order that these activities may develop freely.

Maria Montessori’s quote emphasizes the critical importance of the first three years of life in establishing the foundations of both physical and psychic health. Montessori highlights that during these early years, a child undergoes significant transformations, not just in size but also in key areas like language and movement. She is pointing out that this period of development is crucial for laying the groundwork for a child’s overall well-being and future growth.

The quote also stresses the idea that development in these formative years is not just about physical growth, but also about the psychological and emotional growth that shapes a child's future. The process of learning to speak and control their movement is fundamental to their ability to interact with and make sense of the world. Montessori advocates for an environment where these activities can develop freely, without being hindered or restricted, in order to ensure that the child’s natural growth is supported.

Montessori’s focus on safeguarding the child in these early years reflects her educational philosophy, which emphasizes the importance of a nurturing and supportive environment that allows children to develop at their own pace. The idea is that when children feel safe and supported, they can thrive and reach their full potential, whether in terms of physical health or emotional and cognitive development. Montessori’s method underscores the role of freedom and autonomy in early childhood education.

Originating from Montessori’s work as a pioneering educator and her deep understanding of child development, this quote reflects her belief in the vital importance of early childhood experiences in shaping a person’s future. Montessori’s educational methods, which emphasize hands-on learning and respect for the child’s natural development, were rooted in her conviction that early childhood is a formative period that should be protected and nurtured for the child’s long-term well-being.
