Child abandonment in the context of "Human–animal breastfeeding"

In ancient times, exposition (from the Latin expositus, "exposed") was a method of infanticide or child abandonment in which infants were left in a wild place either to die due to hypothermia, starvation, animal attack or to be collected by slavers or by those unable to produce children.

Following exposure, the infants usually died, were taken by slave traders, or were adopted by others.

In Abrahamic religions, Moses was the Hebrew prophet who led the Israelites out of slavery in the Exodus from Egypt. He is considered the most important prophet in Judaism and Samaritanism, and one of the most important prophets in Christianity, Islam, the Baháʼí Faith, and other Abrahamic religions. According to the Abrahamic scriptures, God dictated the Mosaic Law to Moses, which he wrote down and which formed part of the Torah.

According to the Book of Exodus, Moses was born in a period when his people, the Israelites, who were an enslaved minority, were increasing in population; consequently, the Egyptian Pharaoh was worried that they might ally themselves with Egypt's enemies. When Pharaoh ordered all newborn Hebrew boys to be killed in order to reduce the population of the Israelites, Moses' Hebrew mother, Jochebed, secretly hid him in the bulrushes along the Nile river. The Pharaoh's daughter discovered the infant there and adopted him as a foundling. Thus, he grew up with the Egyptian royal family. After killing an Egyptian slave-master who was beating a Hebrew, Moses fled across the Red Sea to Midian, where he encountered the Angel of the Lord, speaking to him from within a burning bush on Mount Horeb.

A foundling hospital was originally an institution for the reception of foundlings, i.e., children who had been abandoned or exposed, and left for the public to find and save. A foundling hospital was not necessarily a medical hospital, but more commonly a children's home, offering shelter and education to foundlings.

The antecedents of such institutions was the practice of the Catholic Church providing a system of relief, children being left (jactati) in marble shells at the church doors, and tended first by the matricularii or male nurses, and then by the nutricarii or foster parents. But it was in the 7th and 8th centuries that definite institutions for foundlings were established in such towns as Trèves, Milan and Montpellier.

Street children are poor or homeless children who live on the streets of a city, town, or village. Homeless youth are often called street kids, or urchins; the definition of street children is contested, but many practitioners and policymakers use UNICEF's concept of boys and girls, aged under 18 years, for whom "the street" (including unoccupied dwellings and wasteland) has become home and/or their source of livelihood, and who are inadequately protected or supervised. Street girls are sometimes called gamines, a term that is also used for Colombian street children of either sex.

Some street children, notably in more developed nations, are part of a subcategory called thrown-away children, consisting of children who have been forced to leave home. Thrown-away children are more likely to come from single-parent homes. Street children are often subject to abuse, neglect, exploitation, or, in extreme cases, murder by "clean-up squads" that have been hired by local businesses or police.

A single parent is a person who has a child or children but does not have a spouse or live-in partner to assist in the upbringing or support of the child in household together. Reasons for becoming a single parent include annulment, death, divorce, break-up, abandonment, domestic violence, rape, childbirth by a single person or single-person adoption. A single parent family is a family with children that is headed by a single parent.

Childhood trauma is often described as serious adverse childhood experiences. Children may go through a range of experiences that classify as psychological trauma; these might include neglect, abandonment, sexual abuse, emotional abuse, and physical abuse. They may also witness abuse of a sibling or parent, or have a mentally ill parent. Childhood trauma has been correlated with later negative effects on health and psychological wellbeing. However, resilience is also a common outcome; many children who experience adverse childhood experiences do not develop mental or physical health problems.
