Infancy (0-2 years)?

Infancy is the stage of development that begins at birth and lasts until around 2 years of age. During this time, infants experience rapid physical, cognitive, and emotional growth and development. They learn to roll over, sit up, crawl, walk, and eventually talk. Infants also form attachments to their caregivers and begin to develop a sense of trust and security in their environment. This stage is crucial for laying the foundation for future development and learning.
