Donating Breastmilk to Milk Banks: What You Should Know

While many intended parents are overjoyed at the idea of receiving breastmilk from their surrogate, this arrangement is not ideal for everyone. Some parents won’t want to receive milk from you for emotional reasons, while in other cases, supplying the milk becomes logistically impossible.

Being the giving women that they are, we find that many surrogates will still wish to express their breastmilk with the goal of helping other families in need. In addition to helping other families, donating breastmilk can provide a financial boost to a surrogate in the months following the conclusion of her surrogacy journey, making donating milk a positive experience on many levels. For these reasons, many surrogates choose to donate to milk banks.

Milk banks generally appreciate surrogate applicants to their programs as they know they come from a giving, responsible, mature personality set. Here’s a very brief overview of what you can expect if you are considering donating breastmilk to a milk bank following the birth of your surrogate child.

More Screening

Just as with the surrogacy experience, getting started with a milk bank often means another intensive screening process. Most start with an information application and/or phone conversation with their admissions team. Admissions specialist will ask about your pregnancy, medical health, and any medications that you’re on. It’s important to answer honestly.

They Cover the Costs

First of all, know that you’ll need to undergo blood testing before you’re approved to donate to most milk banks. The milk bank will cover this cost. Then, if you’re approved to join a milk bank donation program, know that most banks cover your related costs in addition to any potential payment that they give. Most milk banks will send or reimburse you for collection bags, a breast pump, and pumping accessories. Later, once you’ve collected enough milk, the milk bank generally also covers the cost of the shipping materials and postage for getting the milk to them.

Expect to be Meticulous

Because the majority of milk banks supply milk to premature babies or those with other significant health issues, they have to be very meticulous about the milk they accept. This means that you will be responsible for steam sterilizing all of your accessories before and after every pumping session. You’ll need to keep detailed and exact logs of your output, measure the milk in each collection bag closely, and ensure that the bags are frozen correctly. This generally means learning to freeze milk flat and keep it in a freezer that reaches very specific temperatures. While protocol can differ from milk bank to milk bank, in general, expect to pay close attention to your pumping life.

Expect to Donate A Lot

While output varies between women greatly, most milk banks will ask you to commit to donating a specific amount of milk before leaving their program. This can vary between milk banks but tends to average between 100 and 200 ounces.


You may not be eligible to donate if your blood tests results reveal certain medical conditions, tobacco use, drug use, or other pathogens. Additionally, women who traveled to the United Kingdom from 1980-1996 are sometimes ruled out. Candidates are also generally asked to be in good health and not on regular medications.
