Breasts for hire and shared breastfeeding: wet nursing and cross feeding in Australia, 1900-2000.

Wet nursing and cross-nursing both involve the breastfeeding of a baby by someone who is not the baby's mother. They differ in that wet nurses were usually employees in paid situations and the breastfeeding was not reciprocated, whereas cross-nursing was between peers and was usually unpaid and could be reciprocal. In Australia at the turn of the twentieth century wet nurses were employed in private homes or institutions. By the 1920s, finding a wet nurse had become extremely difficult, but informal cross-feeding existed long after this. This study examines both practices in twentieth century Australia, 1900-2000, and includes a discussion of the decline of human milk banks, another means of sharing mothers' milk.
