The first three critical years of life hide the most crucial growth codes. Parents, please do not miss out on them.

The importance of education from birth (zero-to-three education) was recognized over a century ago by numerous child development specialists. Whether in an infant care center or at home, adults must cultivate an awareness of early childhood education to provide children with a truly high-quality nurturing environment.

Having spent 20 years in early childhood education, I have accumulated vast practical experience and witnessed firsthand how a high-quality nurturing environment impacts a child. What exactly constitutes a high-quality nurturing environment? I like to view it through the lens of three foundational pillars:

The Three Pillars of Education from Birth

1. A Mature and Prepared Adult

Infants and toddlers enter the world like a blank slate. Through tiny fragments of daily routines, they steadily build their sense of self-worth. According to the theory of intersubjectivity, although the subject and object seem to occupy opposing primary and secondary roles, human interaction is actually a continuous process where these roles swap places.

Take a mother and her child as an example: the infant’s world revolves around the mother, while the mother centers her focus on the infant’s needs. In this dynamic, the mother’s love and care reassure the infant that they are loved and protected. Consequently, merely having the mother close by brings the baby pure joy. This positive reaction from the infant, in turn, stimulates the mother, deepening a beautiful parental bond. This is a positive manifestation of intersubjectivity.

However, intersubjectivity is not always positive. For instance, if a primary caregiver lacks the skills to interact with a tiny child, they often grow angry and impatient with the child's crying. The infant senses this lack of complete acceptance, becomes frustrated, and triggers even greater emotional meltdowns. This leaves the caregiver feeling defeated and discouraged. Over time, this dynamic traps both parties in a negative loop of self-worth and behavioral reactions. Common outcomes include highly irritable infants who are difficult to soothe, timid children who are afraid to try new things for fear of making mistakes, short-tempered caregivers, and improper, harsh, or high-pressure parenting methods.

A mature and prepared adult is one who truly understands infants and toddlers. They recognize the vast difference between an adult and a child—including differences in routine schedules, physical environment needs, and the natural milestones of development. For example, a child learning to crawl naturally needs plenty of floor space, rather than being restricted out of a fear of dirt. In other words, when a caregiver offers encouragement and support, it becomes the root of positive interactions, helping the child’s emotions and learning stabilize.

2. A Living Environment That Supports Independence

Before the age of three, a completely immobile infant transforms into an individual capable of basic self-care. The Montessori educational philosophy constantly emphasizes that children possess a powerful, intrinsic motivation to learn—a concept known as "sensitive periods."

At each stage of growth, a child has specific developmental tasks to complete. For example, a toddler learning to walk will practice relentlessly until their bodily balance and muscles can freely master the skill. If the environment provides ample opportunities to walk, the child feels deeply satisfied. Conversely, if adults constantly keep the child strapped in a stroller or held in their arms, the child becomes irritable and frustrated because their inner developmental needs are thwarted. Over time, they may even "assume" they are simply bad at walking and abandon the joyful exploration that comes with independent movement.

A three-year-old is fully capable of eating independently. This includes fetching a cup of water when they are thirsty or scooping their own food based on how hungry they feel. A three-year-old can pack their own belongings; before heading out, they can tidy up their toy box and decide exactly what items to put in their backpack. Both intellectually and physically, this makes the child feel capable and empowered. Furthermore, a three-year-old can independently put on their shoes and clothes—and dressing oneself is an essential foundation for social life.

A three-year-old can absolutely be a confident "little adult," provided that their living environment equips them with appropriately sized items and grants them the time to practice continuously over those first three years to achieve milestone after milestone.

3. Teaching Children Age-Appropriate Behavior

Human society is built on communal living. Over millions of years of evolution, we have formed definite social norms: we cannot snatch items from others out of selfish desire, we cannot disrupt public peace for our own amusement, and we cannot cut in line just because we are in a rush.

To an infant or toddler, these social orders are brand new pieces of knowledge. They discover how to behave through imitation and turn these behaviors into fixed lifestyle habits through extensive practice. By age three, a child has already laid down their fundamental pattern of life, and these habits will profoundly shape their future learning.

Adults, who already understand social order, have an obligation to be role models. Teaching children to read a situation and display age-appropriate behavior is a vital task in upbringing. When we see children running wild, screaming, or mishandling items in a restaurant today, the root issue worth examining is not the child’s state, but rather the role of the primary caregiver. This highlights a common misconception in the wave of "positive education"—granting a child excessive freedom and a skewed sense of respect often results in a parenting catastrophe.

The true essence of child-rearing is "intentional nurturing with educational awareness." We are not just feeding children to make them grow bigger; more importantly, we are teaching them healthy life habits. A child with a sense of order will automatically tidy up their belongings; a child with self-control will wait patiently in line; and a socially competent child can use words to express their emotional state. These are the qualities a three-year-old "little adult" should ideally possess.

While the old proverb "what you see at age three seals your destiny at eighty" might sound a bit extreme, it holds a profound truth. The first three years of life are indisputably the period of the most dramatic transformation in a human existence.

Before age three, a child undergoes an explosion in brain development, a massive accumulation of language learning, rapid motor skill progression, intensive imitation of social interactions, and the cementing of lifelong habits.

The first three critical years of life hide the most crucial growth codes. Adults must cultivate an awareness of early childhood education to provide children with a truly high-quality nurturing environment.
