An infant is a very young child, typically one who is less than one year old. This term often refers specifically to a baby during its earliest stages of life, characterized by rapid growth and development. The word originates from Latin 'infans', meaning 'unable to speak, speechless', which emphasizes the early developmental stage of children. Infants are largely dependent on adults for care and nurturing.
