What is the age range defined as infancy?

Infancy is defined as the period from birth to one year of age. During this stage, infants undergo rapid physiological and developmental changes, including growth in motor skills, cognitive abilities, and sensory perception. Understanding this age range is critical for EMTs and healthcare providers as it influences both assessment and treatment decisions.

The first year of life is characterized by specific developmental milestones, such as rolling over, sitting up, and beginning to crawl. These developmental markers can help providers assess the health and well-being of infants during their care. Recognizing the parameters of infancy is essential in emergency situations, where age-specific protocols may be applied, and where the needs of this vulnerable age group differ significantly from older children and adults.

The other age ranges provided do not accurately reflect the established definition of infancy, which is why they are less suitable in this context.
