About the Milk Bank

Who benefits from Human Donor Milk?

There are approximately 1500 low birth weight babies in hospitals across Ontario a year and 70% of don’t have access to a full supply of their mother’s own milk, leaving them with reduced vital nutrients and protective properties. Donor milk could reduce their risk of life-threatening medical complications. The families of medically fragile babies will benefit from knowing that there is donor breastmilk available for their baby to supplement mother’s own supply.

What may prevent a mother from being able to provide milk for her own baby?

Most mothers wish to provide breast milk for their sick or preterm baby but may not be able to provide a full volume of milk due to:

  • Maternal illness or delivery complications that delay the establishment of a milk supply.
  • Insufficient supply if pumping for multiple births (i.e. twins).
  • Stress of having a hospitalized, sick baby.
  • Lack of hormonal stimulation from not being able to put the baby to the breast.
  • Chronic infection or medical condition that precludes breastfeeding.
  • A breast infection that temporarily affects milk production.
  • Geographical separation from the baby.

What is the guidance for donor milk usage for preterm babies of Islamic faith?

In Islam, the issue of using donor milk raises the question of whether this establishes kinship between the donor family and the infant receiving the donor milk.

In 2004, in response to this concern, well known religious scholars, backed by the European Council of Fatwa and Research issued a detailed ruling. The ruling stated that there is no barrier in Islam either to establish milk banks or to make use of them and that this type of feeding does not institute kinship.

My family follows a strict vegan/vegetarian diet. Does the Milk Bank screen donors based on the diet of donor mothers?

Each batch of donor milk is comprised of human milk from four to five donors, to blend for nutrients. We screen for adequacy of the diet of donor, but we do not have batches of donor milk from solely vegetarian or vegan mothers.

For babies who are born preterm or who are medically fragile, studies have shown that human milk provides not only nutrition, but also protection from some of the most severe health complications.

I am a Milk Bank donor, and I am now sick. Can I still donate my milk?

To maintain your milk supply during seasonal illnesses, it is important to continue to breastfeed your baby, or pump your milk on the same schedule as before you became ill.

It is fine to take an occasional acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) as the small amount that may transfer into breast milk is safe for milk donation. Certain cold and flu medications, cough syrups, and other over the counter medications may require a deferral period before pumped milk can be donated.
