During which age range is an individual considered an infant?

An individual is considered an infant typically within the age range of 1 month to 1 year. This classification is important in developmental psychology and pediatrics, as it encompasses a crucial period of rapid growth and development in various domains including physical, cognitive, and emotional maturation. During this stage, infants undergo significant milestones, such as learning to crawl, walk, and develop basic communication skills. Recognizing this age bracket helps in assessing developmental progress and determining appropriate care and educational practices tailored to their needs. The other options either specify a too narrow age range or extend beyond the standard definition of infancy, which generally does not categorize individuals beyond their first year of life as infants.
