Scientific understanding of early brain development reveals why children’s development, especially from birth to age five, forms the foundation for a stable and thriving society. Research on early childhood development not only enhances policy and practices for children’s growth but also encourages new approaches and perspectives in decision-making. Harvard University’s Center on the Developing
Child outlines eight essential aspects of early child development:

1. Severe stress from the family and environment can significantly impact even newborns and young children.
Negative experiences in infancy or early childhood can lead to physical and chemical changes in the brain that may persist throughout life. The biological alterations associated with these experiences can affect multiple organ systems, increasing the risk of learning, behavioral, physical, and mental health issues later in life.

2. Child development is a highly interactive process, not defined solely by genetics.
The environment, both before birth and soon after, provides impactful experiences that chemically alter specific genes, influencing the degree and timing of their expression. While genetic factors play a role, environmental factors can reshape family legacies, impacting self-control, attention, and memory development in children.

3. Infants form primary attachments with parents, essential for holistic development.
Relationships with other caregivers—both within and outside the family—offer substantial benefits. Stable relationships with accessible caregivers strengthen social and emotional growth. Inconsistent caregivers in early childhood programs can disrupt the development of secure expectations, as children need predictable responses to their needs.

4. Basic brain architecture forms within the first three years of life, though developmental opportunities continue beyond age three.
Early experiences strongly shape essential functions, such as vision, hearing, and some aspects of emotional growth. Although early experiences affect higher-level brain functions, these regions continue developing through adolescence, offering chances to counterbalance early influences even in adulthood.

5. Severe neglect can be as detrimental, if not more, than physical abuse.
Children who experience prolonged neglect often face cognitive and behavioral challenges. These findings suggest early unstable relationships may impact brain development more than physical trauma, despite neglect receiving less attention.

6. Children who have experienced violence don’t necessarily develop stress disorders or become violent.
Although early trauma affects brain development and may increase aggression, timely support from reliable caregivers and necessary treatment can significantly improve outcomes, proving that children are not doomed to poor outcomes.

7. Removing a child from a dangerous environment doesn’t eliminate the impact of past experiences.
It’s essential to provide traumatized children with safe and predictable environments that restore a sense of control. This often requires therapeutic support for full recovery.

8. Resilience requires supportive relationships, not strict individualism.
Children can adapt and thrive even under challenging circumstances. Resilience depends on reliable, supportive relationships, often with caregivers, combined with biological resistance to adversity, rather than merely relying on individual courage.
