What age range defines the life stage of Infancy?

Infancy is generally defined as the period of life from birth to around 2 years of age. This stage is crucial for physical, emotional, and cognitive development. During this time, infants undergo significant changes, including rapid growth, the development of motor skills, and the formation of attachment relationships.

The selection of the 0-3 years range may stem from a broader perspective on childhood development, but it is more typical to classify infancy as specifically up to 2 years. This period is followed by early childhood, which extends from the age of 2 until about the age of 5. Recognizing these stages allows caregivers and health practitioners to provide appropriate developmental support and interventions tailored to the specific needs of infants and young children.
