For infanticide among animals, see Infanticide (zoology). Infanticide (or infant homicide) is the intentional killing of infants. Parental infanticide researchers have found that mothers are far more likely than fathers to be the perpetrator for neonaticide and slightly more likely to commit infanticide in general. In many past societies, certain forms of infanticide were considered permissible.
An infant (from the Latin word infans, meaning unable to speak or speechless) is the more formal or specialised synonym for baby, the very young offspring of a human or other animal. A newborn is, in colloquial use, an infant who is only hours, days, or up to a few weeks old. In medical contexts, newborn or neonate (from Latin, neonatus, newborn) refers to an infant in the first 28 days after birth; the term applies to premature, full term, and postmature infants; before birth, the term fetus is used.
