A frequent method of infanticide in ancient Europe and Asia was simply to abandon the infant, leaving it to die by exposure (i.e., hypothermia, hunger, thirst, or animal attack).
[9] The anthropologist Raymond Dart has interpreted fractures on the skulls of hominid infants (e.g. the Taung Child) as due to deliberate killing followed by cannibalism, but such explanations are by now considered uncertain and possibly wrong.
[10] Children were not necessarily actively killed, but neglect and intentional malnourishment may also have occurred, as proposed by Vicente Lull as an explanation for an apparent surplus of men and the below average height of women in prehistoric Menorca.
[38][39][40]In some periods of Roman history it was traditional for a newborn to be brought to the pater familias, the family patriarch, who would then decide whether the child was to be kept and raised, or left to die by exposure.

There are a large number of cases of what are called newly-born children, which are found all over England, more especially in London and large towns, abandoned in streets, rivers, on commons, and so on... [A] great deal of that crime is due to what are called lying-in houses, which are not registered, or under the supervision of that sort, where the people who act as midwives constantly, as soon as the child is born, either drop it into a pail of water or smother it with a damp cloth.
Belief in reincarnation allowed poor residents of the country to kill their newborn children if they felt unable to care for them, hoping that they would be reborn in better circumstances.
Furthermore, 18th and 19th century Qing reports of villagers in Liaoning show that they did not consider newborn children fully human, instead regarding life as beginning at some point after the sixth month after birth.
The magnitude of this practice is subject to some dispute; however, one commonly quoted estimate is that, by late Qing, between one fifth and one-quarter of all newborn girls, across the entire social spectrum, were victims of infanticide.
[76][77][78] Scottish physician John Dudgeon, who worked in Peking, China, during the early 20th century said that, "Infanticide does not prevail to the extent so generally believed among us, and in the north, it does not exist at all.

[209] Current diagnostic considerations include symptoms, psychological history, thoughts of self-harm or harming one's children, physical and neurological examination, laboratory testing, substance abuse, and brain imaging.
In other places, like the United States, safe-haven laws allow mothers to anonymously give infants to designated officials; they are frequently located at hospitals and police and fire stations.
[214] According to studies carried out by Kyoto University in primates, including certain types of gorillas and chimpanzees, several conditions favor the tendency to kill their offspring in some species (to be performed only by males), among them are: Nocturnal life, the absence of nest construction, the marked sexual dimorphism in which the male is much larger than the female, the mating in a specific season and the high period of lactation without resumption of the estrus state in the female.
An instance in which a child born on an inauspicious day is to live or die according to the chance of being trampled by cattle (death being likely) is provided by Infanticide in Madagascar, painted by Henry Melville and engraved by J Redaway for Fisher's Drawing Room Scrap Book, 1838 with a poetical illustration and notes by Letitia Elizabeth Landon.
