Over the past year at QEII, we have noticed an increase of interest by our clients in the use of donor breast milk. An increasing trend is informal breast milk sharing where families post a request on social media sites. At the Queen Elizabeth II Family Centre (QEII), we believe families need to be fully informed about the risks of using unscreened breast milk or the use of pasteurised donor human milk from a human milk bank and balance these with their decision about feeding their child.
The World Health Organization (WHO) states that ‘breastfeeding is an unequaled way of providing ideal food for the healthy growth and development of infants’. Breastfeeding is beneficial to infants, mothers, families and society. Reliable evidence shows that breastfed babies are less likely to suffer from necrotising enterocolitis (NEC), diarrhoea, respiratory illness, middle ear infection, type 1 diabetes, allergies and childhood leukaemia. Reliable evidence also shows that breastfed babies have enhanced cognitive development. Breastfeeding also benefits mothers by promoting faster recovery from childbirth, reducing the risks of breast and ovarian cancers in later life, and reduced maternal depression.
In Australia, it is recommended that infants are exclusively breastfed until around 6 months of age when solid foods are introduced, and that breastfeeding is continued until 12 months of age and beyond, for as long as the mother and child desire. The Australian Society for Clinical Immunology and Allergy (ASCIA) advises that when an infant is ready, at around six months, but not before 4 months, start to introduce a variety of solid foods, starting with iron rich foods, while continuing breastfeeding. Breastfeeding during the period that a variety of solids are first introduced may help reduce the risk of the infant developing allergies and food intolerances.
Most women choosing to breastfeed can do so successfully and there are only a few rare circumstances in which breastfeeding is not recommended. However, where it is not possible for a biological mother to breastfeed the WHO recommends human milk from other sources, especially for the preterm and low birth weight baby, as the most preferred alternative option and the establishment of human milk banks.
Human milk banks and breastmilk sharing in Australian maternity hospitals were widespread until the 1980’s, when concerns were raised about the transmission of blood borne viruses such as HIV and Cytomegalovirus. With growing evidence supporting the benefits of giving human milk to premature babies and recognition that screening donors and pasteurising human milk could virtually eliminate risk, milk banks were re-introduced with the first opening in Perth, WA in 2006. There are now four hospital and one community based milk banks operating in Australia, none at this stage in the ACT.
Preterm and low birth weight babies are at higher risk than healthy term babies for a range of life threatening conditions such as NEC and infections. It is now widely accepted in neonatal intensive care units that it is best practice for mothers to breastfeed or express milk to feed their babies. When this is not possible, reliable evidence shows, while not quite as protective as a mother’s own milk, pasteurised donor human milk is associated with better outcomes and a reduced risk of NEC compared to infant formula, as well as significant savings to the health care system.
The practice of wet nursing, where a woman breastfeeds another’s child, was common before feeding bottles and infant formula were introduced. Anecdotally, this is still practiced in Australia with sisters or friends with similar aged babies sharing breast feeding and in some Australian communities, sharing the breastfeeding of babies is the cultural norm.
More recently, increasing awareness of the benefits of breast milk, the idea of donor milk and the rise of social media have led to the establishment of websites supporting informal milk sharing arrangements and helping connect families seeking donor milk with mothers wishing to give away or sell their excess milk. Under Australian law, it is illegal to buy or sell parts of the human body, including breast milk.
The Australian Breastfeeding Association (ABA) and the Australian College of Midwives (ACM) both have position statements on donor milk encouraging mothers to be aware of the risks associated with privately sourced donor milk. Milk banks extensively screen the donor, provide information on best practice for hygienic collection, storage and transportation, pasteurise the milk and test for the presence of pathogens. With informal sharing of breast milk there is a small, but real, potential risk of transmission of diseases including HIV and Hepatitis C through unscreened breast milk. In addition, there are the risks of bacterial contamination and exposure to medications, drugs or other substances and no guarantee that milk obtained from the internet or other informal sources is actually breast milk.
At QEII we support families making informed choices and encourage them to weigh up the risks and benefits when considering feeding options and choosing where to source milk for their child. At the same time we hope in the future Canberra is home to its own milk bank.
