Infanticide (or infant homicide) is the intentional killing of infants or offspring. Infanticide was a widespread practice throughout human history that was mainly used to dispose of unwanted children, its main purpose is the prevention of resources being spent on weak or disabled offspring. Unwanted infants were normally abandoned to die of exposure, but in some societies they were deliberately killed. Infanticide is now widely illegal, but in some places the practice is tolerated or the prohibition is not strictly enforced.
