New study examines the resurgence of milk sharing

Pediatric Academic Societies

BALTIMORE - A new study examines the history and resurgence of milk sharing. Findings from the study will be presented during the Pediatric Academic Societies (PAS) 2019 Meeting, taking place on April 24 - May 1 in Baltimore.

Wet nursing was considered the safest and most popular alternative form of nutrition until further options were invented, leading to the eventual decline in the profession. Now, society is seeing a resurgence in milk sharing practices through women with an oversupply who are storing extra breast milk and selling it. Unlike wet nursing, however, these interactions often take place away from the regulations and medical examinations that once kept this practice relatively safe.

"While the practice of milk sharing has been around for centuries (as highlighted in this abstract), unregulated milk sharing via the internet presents safety concerns and is therefore discouraged," said Ruth Milanaik, DO, one of the authors of the study. "Physicians should be aware of the resurgence of this practice and encourage participation in regulated milk sharing via milk banks."

Practices of milk sharing can be traced to 2000 B.C., when wet nurses would breastfeed a child that was not biologically their own. At this time, wet nurses played a vital, lifesaving role in feeding infants who had no alternative form of nutrition if their mother could not provide enough breastmilk herself. Wet nursing evolved into a well-regulated profession, with laws and contracts that governed its practice, including a requirement for completion of a medical examination before being registered.

Though commonplace, wet nursing did also face widespread criticism from those concerned about its effect on the mother-infant bond as well as the risk of disease transmission (exacerbated by the low socioeconomic status of many wet nurses). Despite these objections, the lack of hygienic bottles, suitable infant formula, and proper food sterilization techniques (to allow for storage of breastmilk) left feeding via wet nurse as the only safe alternative to a mother's own breastmilk for centuries. It was not until these inventions in the 18th and 19th century--combined with society's historical distrust of wet nurses--that wet nursing fell out of popularity.

Physicians must understand the history of milk sharing--the important role it once played and its previous status as a well-regulated profession--in order to best advocate to patients and to policymakers for safer sharing practices and regulations.

"This project was actually borne out of another study we were conducting looking into the milk sharing practices of parents of newborns," said Nikita Sood, one of the authors of the study. "We thought it was important to examine the history of this practice so that we could better understand the culture around milk sharing and advocate for safe sharing of human milk."

Sood will present findings from "The Resurgence of the Wet Nurse" on Saturday, April 27 at 8 a.m. EDT. Reporters interested in an interview with Sood should contact PAS2019@piercom.com. Please note that only the abstracts are being presented at the meeting. In some cases, the researchers may have additional data to share with media.

The PAS 2019 Meeting brings together thousands of pediatricians and other health care providers to improve the health and well-being of children worldwide. For more information about the PAS 2019 Meeting, please visit http://www.pas-meeting.org.

About the Pediatric Academic Societies Meeting

The Pediatric Academic Societies (PAS) Meeting brings together thousands of pediatricians and other health care providers united by a common mission: to improve the health and well-being of children worldwide. This international gathering includes pediatric researchers, leaders in pediatric academics, clinical care providers and community practitioners. Presentations cover issues of interest to generalists as well as topics critical to a wide array of specialty and sub-specialty areas. The PAS Meeting will be the premier North American scholarly child health meeting. The PAS Meeting is produced through a partnership of four pediatric organizations that are leaders in the advancement of pediatric research and child advocacy: American Pediatric Society, Society for Pediatric Research, Academic Pediatric Association and American Academy of Pediatrics.

Abstract: The Resurgence of the Wet Nurse

Background: The last few years have seen a rise in informal milk sharing among breastfeeding mothers who are able to connect online to buy and sell their breast milk. Though this practice is discouraged by the medical community due to safety concerns, milk sharing is not a new phenomenon. In order to understand the motivations for milk sharing and encourage safe practices, we must first examine the origins and historical significance of milk sharing.

Objective: To understand the history of milk sharing.

Design/Methods: Scholarly literature regarding the history of infant feeding, wet nursing, and milk sharing were reviewed.

Results: Practices of milk sharing can be traced to 2000 B.C., when wet nurses would breastfeed a child that was not biologically their own. At this time, wet nurses played a vital, lifesaving role in feeding infants who had no alternative form of nutrition if their mother could not provide enough breastmilk herself. Wet nursing evolved into a well-regulated profession, with laws and contracts that governed its practice, including a requirement for completion of a medical examination before being registered. Though commonplace, wet nursing did also face widespread criticism from those concerned about its effect on the mother-infant bond as well as the risk of disease transmission (exacerbated by the low socioeconomic status of many wet nurses). Despite these objections, the lack of hygienic bottles, suitable infant formula, and proper food sterilization techniques (to allow for storage of breastmilk) left feeding via wet nurse as the only safe alternative to a mother's own breastmilk for centuries. It was not until these inventions in the 18th and 19th century--combined with society's historical distrust of wet nurses--that wet nursing fell out of popularity.

Conclusion(s): Milk sharing is a practice that has been around for centuries. Wet nursing was considered the safest and most popular alternative form of nutrition until further options were invented, leading to the eventual decline in the profession. Now, society is seeing a resurgence in milk sharing practices through women with an oversupply who are storing extra breast milk and selling it. Unlike wet nursing, however, these interactions often take place away from the regulations and medical examinations that once kept this practice relatively safe. Physicians must understand the history of milk sharing--the important role it once played and its previous status as a well-regulated profession--in order to best advocate to patients and to policymakers for safer sharing practices and regulations.
