INFANCY

n. babyhood, state or period of being an infant, early childhood

In basic English usage, an infant is defined as a human child at the youngest stage of life, specifically before they can walk and generally before the age of one (see also child and adolescent).The term "infant" derives from the Latin word in-fans, meaning "unable to speak." There is no exact definition for infancy. "Infant" is also a legal term with the meaning of minor; that is, any child under the age of legal adulthood.A human infant less than a month old is a newborn infant or a neonate. The term "newborn" includes premature infants, postmature infants and full term newborns.
