In pediatric definitions, what age correlates with the term 'infant'?

The term 'infant' in pediatric definitions specifically refers to the age range from 28 days to 1 year. This classification is important in the medical field as it helps healthcare providers to understand the developmental and physiological characteristics that are specific to this age group. Infants undergo rapid growth and development, and their physiological responses differ significantly from those of older children and adults.

For effective assessment, treatment, and interventions, it's crucial to recognize the unique needs of infants, which is why this age range is distinctly defined. Understanding this classification aids practitioners in delivering age-appropriate care and addressing the specific health concerns that may arise during this critical period of development.
