Learning in the earliest stage of life--the infancy, toddlerhood and preschool period--is relational and rapid. Child-initiated and adult-mediated conversations, playful interactions and learning through active involvement are integral to young children making sense of their environments and to their development over time. The child's experience in this early phase of life is at the heart of "Learning to Be" in any society. This article reviews early learning studies aimed at understanding children's personal, intellectual and social development, and promoting that development. Particular reference is made to attachment and attention, the process of self-regulation, and the adult-child engagement strategies that advance the child's receptive and expressive language: these all exercise substantial influence on early childhood learning and child development outcomes over time. The selected research studies variously highlight the development of infants, toddlers, and young children in kindergarten and the early years of school, and how children make sense of their environments as social, learning and unique human beings. Both the home learning environment and early childhood education programmes are important in children's development. This article argues for high-quality early childhood experience and giving attention to the engagement role of adults in advancing young children's development, minimising the risk of poor development and supporting positive long-lasting personal, academic and social benefits. In this early phase of life, in the words of Jacques Delors: "… none of the talents which are hidden like buried treasure in every person must be left untapped". (Delors et?al. 1996, p. 23).
