That right begins in early childhood, which is one reason why the Sustainable Development Goals (SDGs) call on governments to "ensure that all girls and boys have access to quality early childhood development, care and pre-primary education." Investment in quality early childhood care and education produces a double benefit: It is both fair and efficient. This kind of holistic approach also takes child protection into account and focuses on the quality of care provided to infants and young children. A long-term study in Jamaica found a 42 per cent increase in average adult earnings associated with early childhood stimulation.
