In premodernity, a time when human milk was the only safe means of infant nutrition, and in societies, such as those of classical antiquity and early Byzantium, where breastfeeding was considered servile work, wet-nursing was both a necessary and widespread occupation. Despite the social demand for the profession, public discourses around wet nurses were mostly negative, while their work was treated with both admiration and scorn. In an attempt to understand ancient and early Byzantine approaches to the wet nurse, this article takes a matricentric perspective. It investigates various discourses (rhetorical, moralist, philosophical, theological, hagiographical, medical and contractual) which establish the wet nurse as an essential part of the institution of motherhood, as a social and moral category whose work, way of life and behaviour are constantly defined, controlled and regulated. These discourses nevertheless tell us much more about the anxieties and preoccupations of the societies that produced them and much less about actual contemporary wet nurses. The choice of an investigation encompassing antiquity up to early Byzantium, an extension rarely seen in existing studies, further illuminates the mechanics and dynamics of the ideologies around the wet nurse, as these are preserved or evolve in time.

Mughal chronicles frequently refer to royal Mughal infants being entrusted to wet nurses for breastfeeding and nurturing. The women chosen for this purpose were invariably the wives of important Mughal officials. It was believed that the quality of milk the baby received determined its future disposition. Therefore, these nurses needed to possess desirable psychological qualities and moral temperaments. They were accorded a high status and usually established a lasting relationship with their charges. As a result, the children of the emperor developed a close association with their wet nurses and their families who, in turn, became the staunchest supporters of their wards. The success, influence, and prestige of these families depended on the political fortune of the royal child they had cared for. If the prince became an emperor, they gained immense power and prestige both in life and death. They were honoured with elaborate funerals and buried in imperial tombs. This article argues that the rationale behind the use of wet nurses by Mughal royalty during Emperor Akbar's reign was not simply a medical or physiological one, it was equally a political instrument for forging ties between prominent families and royalty.

This essay proposes that “milk kinship,” which upper-class individuals in premodern Japan formed with their milk kin—a menoto (wet nurse) and a menotogo (foster sibling)—occupies the core of an institutionalized erotic fosterage. In this “menoto system,” the surrogate mother's lactating body and erotic-affective labor became the connective tissue to bind two interclass families, creating a symbiosis that fortified the existing sociopolitical power structures. Around the tenth century, many vernacular tales started to feature menoto characters. While a typical menoto is the protagonist's homely, asexual, motherly confidante, her derivative construct—the menotogo of the protagonist—is often cast in an erotic light. In the four texts examined in this essay, menotogo valorize their erotic agencies to benefit their charges through sexual-affective labor or through an indirect method. The latter entails the formation of a “love square” in which two menotogo become lovers and then help their respective charges do the same.
