The importance of ages 0-3 years
In the first moments, months and years of life, every touch, movement and emotion in a young childs life translates into an explosion of electrical and chemical activity in the brain, as billions of cells are organizing themselves into networks requiring trillions of synapses between them (see Panel 1). These early childhood years are when experiences and interactions with parents, family members and other adults influence the way a childs brain develops, with as much impact as such factors as adequate nutrition, good health and clean water. And how the child develops during this period sets the stage for later success in school and the character of adolescence and adulthood.
When infants are held and touched in soothing ways, they tend to thrive. Warm, responsive care seems to have a protective function, to some extent immunizing an infant against the effects of stress experienced later in life. But the brains malleability during these early years also means that when children do not get the care they need, or if they experience starvation, abuse or neglect, their brain development may be compromised (Panel 1).
The effects of what happens during the prenatal period and during the earliest months and years of a childs life can last a lifetime1. All the key ingredients of emotional intelligence confidence, curiosity, intentionality, self-control, relatedness, capacity to communicate and cooperativeness that determine how a child learns and relates in school and in life in general, depend on the kind of early care he or she receives from parents, pre-school teachers and caregivers.2 It is, of course, never too late for children to improve in their health and development, to learn new skills, overcome fears or change their beliefs. 3 But, as is more often the case, when children dont get the right start, they never catch up or reach their full potential.
Why invest? The rights of children and the cause of human development4 are unassailable reasons for investing in early childhood. The neurosciences provide another rationale thats hard to refute as they demonstrate the influences of the first three years on the rest of a childs life.
In addition5, there are also compelling economic arguments: increased productivity over a lifetime and a better standard of living when the child becomes an adult, later cost-savings in remedial education and health care and rehabilitation services and higher earnings for parents and caregivers who are freer to enter the labour force.
And there are social reasons as well: Intervening in the very earliest years helps reduce the social and economic disparities and gender inequalities that divide a society and contributes to including those traditionally excluded.
And political reasons: A countrys position in the global economy depends
on the competencies of its people and those competencies are set early
in life before the child is three years old.6
