An infant or baby is the very young offspring of humans. A newborn is an infant who is within hours, days, or up to a few weeks from birth. In medical contexts, newborn or neonate (from Latin, neonatus, newborn) refers to an infant in the first 28 days of life (from birth up to 4 weeks after birth, less than a month old). The term "newborn" includes premature infants, postmature infants and full term newborns. The term infant is derived from the Latin word infans, meaning "unable to speak" or "speechless." It is typically applied to children between the ages of 1 month and 12 months; however, definitions vary between birth and 3 years of age.
