Abstract
This article explores the meaning and definitions associated with the concept of childhood over time. It sheds light on the social, cultural, and historical constructions of the term childhood and the imperative to understand the context in which it is used. The evolving nature of the definition in respect to the age range associated with childhood indicates evolving trends in developmental research. Discussions about these trends are timely in recognizing their significance for shaping national and international policies and practices that will contribute to children's development and well-being in the new millennium.
