What is the age range for an infant?

• A. One month to one year
• B. Birth to twelve months
• C. Newborn to six months
• D. Six months to two years

Answer: (A)

Infant age covers roughly the first year of life, typically from about one month old up to 12 months. This keeps newborns in a separate neonatal category and ends before the toddler period begins, which makes one month to one year the standard infancy range in many EMS and pediatric contexts. Starting at birth would include newborns, ending at six months would miss later infancy, and six months to two years would include toddlers beyond infancy.
