What stage of development is referred to as infancy?

Infancy is defined as the developmental stage that occurs from birth to 2 years old. During this period, individuals experience rapid growth and significant developmental milestones, including physical, cognitive, and emotional changes. The brain develops at a remarkable rate, and infants begin to form attachments, learn to crawl and walk, and start to communicate. This stage sets the foundation for future development, making it a crucial time in a person's life. Understanding infancy helps caregivers and professionals support healthy growth and address the needs of young children effectively.
