What term is used to describe a newborn infant?

The term "neonate" is specifically used to refer to a newborn infant, particularly during the first month of life. This period is critical for development as the infant undergoes significant physiological changes and begins to adapt to life outside the womb. The term emphasizes the distinct transitional phase that occurs immediately after birth, during which the newborn's body systems start functioning independently.

In contrast, "fetus" refers to the developing baby in the womb, typically from the ninth week after conception until birth. "Child" generally refers to an individual who is in the early stages of life beyond infancy, usually considered to be from one year to puberty. "Adolescent" refers to an individual who is in the teenage years, marked by significant emotional and physical development towards adulthood. Each of these terms defines different stages in human development, underscoring the unique characteristics and milestones associated with each phase.
