Definition and Pronunciation
Infancy is the earliest stage of humanlife, beginning at birth and continuing through the first year or two of life, depending on the medical, legal, or developmental context. During infancy, growth and development occur more rapidly than at almost any other stage of life.
Pronunciation: IN-fuhn-see
Easy Explanation
Infancy is the period immediately after birth when a baby grows quickly and learns basic skills such as feeding, recognizing caregivers, smiling, sitting, crawling, and eventually taking first steps. During this stage, the brain, body, and nervous system develop rapidly.
Infancy is followed by childhood, which continues the process of physical, emotional, intellectual, and social development.

Connection to Sexuality

Parents and caregivers may begin teaching children the correct names for body parts and respecting body privacy in simple, age-appropriate ways as children grow.
Understanding infancy helps people learn about early human development, parenting, child health, and the foundations of later physical, emotional, and social well-being.
