Donating Milk

Pasteurized human milk is dispensed by prescription only and used only for pre-term or sick hospitalized babies. Once you are accepted as a donor, you will receive an information package outlining the precautions to be taken to ensure the safety and quality of your milk donation. It will include techniques for careful hand-washing, proper cleaning of breast pumps and correct storage and transport of your frozen breastmilk.

Some mothers have already pumped and frozen their breastmilk; others begin to collect milk after contacting the Milk Bank. Previously collected milk can be accepted if a mother passes the necessary screening (for example no medications taken during the time of milk collection), and the milk has been stored and frozen in appropriate breastmilk freezer bags or food grade bottles for an acceptable length of time.

Surplus breastmilk can be pumped after nursing your baby at one feeding per day, after several feedings per day, or by feeding your baby using one breast and pumping the other breast to donate. Individual strategies can be discussed with the Milk Bank Lactation Consultant that are unique to each mother/baby pair and are always based on the adequate growth of the mother’s own baby.
