Mothers Who Engage in Long-Term Informal Milk Sharing

Factors associated with informal human milk sharing among donors and recipients: A mixed-methods systematic review

BACKGROUND

The multiple benefits associated with the provision of human milk exceed individual health outcomes, engendering substantial economic, societal and environmental domains. Human milk is the absolute, unparalleled source of nutrition for infants. Informal human milk sharing is a modernistic and rapidly progressing practice. No systematic review of the factors associated with this contemporary practice among donors and recipients of informal human milk sharing exists.

AIM

The aim of this review was to identify, evaluate, synthesize and integrate the evidence on the factors associated with informal human milk sharing among donors and recipients.

METHODS

A mixed methods systematic review was conducted according to the Joanna Briggs Institute methodological guidance utilizing a convergent integrated approach. The following databases were systematically searched: CINAHL, Scopus, Medline and Embase and Web of Science between inception to August 2023. A grey literature search was conducted using multiple techniques. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

RESULTS

Twenty-four studies were included in this review. Ten integrated findings relating to the factors associated with informal human milk sharing among donors and recipients were identified. The four integrated findings pertaining to donors included: altruistic motivation and value, resistance to commercialization and overcoming inaccessibility, uniting digital and personal connectedness and lack of awareness and acceptance of informal human milk sharing in healthcare settings. The six integrated findings relating to recipients included: maternal or infant factors, superiority and advantageous impact of breastmilk, human milk bank influences, digital connections and transparency, healthcare professional facilitation of informal human milk sharing, and professional and logistical implications.

CONCLUSION

This review highlighted a multitude of factors that motivate, facilitate and impede the practice of informal human milk sharing. Future research is required to explore these factors further within broader geographical locations to enhance the generalizability and rigor of the body of knowledge. Further studies should consider the exploration of the experiences and psychological impact of informal human milk sharing on donors and recipients. The provision of human milk to all infants is an imperative public health endeavor and thus positioning this as a key benchmark for research and practice is crucial.

Human Milk Sharing in the United States: A Scoping Review

Background: Human milk is the optimal form of infant nutrition. If mother's own milk is unavailable, families may seek alternative sources of human milk through milk sharing, despite potential health and safety risks with this practice. Objective: The purpose of this scoping review was to synthesize the current literature on human milk sharing in the United States to help health care professionals better understand how families may use this practice for infant nutrition. Methods: A systematic search was conducted in June 2021 using Ovid MEDLINE, Embase, CINAHL, ProQuest Central, Web of Science, and Google Scholar. Articles were included if the primary outcome was milk sharing, excluding milk banks and preterm hospitalized infants. Results were limited to studies conducted in the United States and published in English after January 1, 2000. Results: From 2,124 articles, 34 met inclusion criteria and were reviewed. Study designs were largely observational (30/34), and participants were predominantly white, married, and middle-income women experiencing lactation problems or in possession of excess breast milk. Milk sharing, not for profit, was often facilitated through the internet but exchanged in person. Conversely, for-profit milk sharing often involved shipping and studies found evidence of milk contamination. No studies documented infant harm. Conclusions: There is limited research on the milk quality and relative risks of milk sharing, and no research on clinical outcomes in infants fed shared milk. Clinicians have opportunities to engage in open conversations about this practice to guide risk mitigation, however, research on recipient infant outcomes are urgently needed to inform best practices.

Care During Pregnancy, Childbirth, Postpartum, and Human Milk Feeding for Individuals Who Identify as LGBTQ

The growing number of families that include members of sexual and/or gender minority (SGM) groups requires perinatal nurses to know how to provide respectful and affirming care to all people, including this population. Approximately 19% of adults who are members of SGM groups are raising 3 million children, with many hoping to become pregnant, foster, use surrogacy, or adopt in the future. Based on current literature, many nurses are not prepared to meet the clinical needs of patients who are members of SGM groups in the maternity setting. Likewise, patients and families of SGM groups often perceive that nurses are uncomfortable with providing care and are not always satisfied with their care. To meet these needs, it is important that nurses use strategies focused on promoting respectful, affirming care, reducing negative experiences, and eliminating marginalizing language and practices. Nurses must incorporate a holistic care focus for patients who are members of SGM minority groups that includes standardized strategic education; development of Lesbian, Gay, Bisexual, Transgender, Queer, Questioning, or Plus (LGBTQ+) affirming and inclusive policies, practices, and language; flexibility, personal reflection of self-bias; and creating an environment of individualized compassionate care.
