What age range defines an infant?

The term "infant" is generally defined as a child in the earliest stage of life, typically from birth to 12 months. While options may suggest varying definitions of age ranges, the most widely accepted understanding considers infants to be children under the age of 1 year. This period is critical for rapid physical, cognitive, and social development, which is why it is specifically categorized as the infancy stage.

The correct age range that defines an infant is indeed less than 2 years when considered in broader contexts, but the more precise definition focuses specifically on the first year of life. This distinction highlights the early developmental milestones that occur during this period.

It's beneficial to recognize the significance of this age range in various contexts, such as healthcare and early childhood education, where the focus on particular growth and developmental needs is paramount. While some options may start from unconventional points or combine ages beyond the standard definition, they don't align with the widely accepted definition that an infant is typically considered to be up to 12 months old.
