Childhood is a beautiful phase of life for most of us. It is a period associated with play, fantasy, and innocence. It is the crucial phase in life and involves important aspects of growth and development which are critical for the entire life span.

The childhood period can be further classified into four sub-stages:

  1. Infancy (birth to 2 years)

  2. Early childhood (2 to 6 years)

  3. Middle childhood (6 to 11 years)

  4. Adolescence (12 to 19 years)

Infancy provides the foundation for all areas of development. It is a period marked by extremely rapid physical growth and development of sensori-motor skills. Infancy is also important for cognitive, language and socio-emotional development.
