If you’re expressing breast milk, chances are you’ll need to store and/or transport it in order to feed your baby at a later time. And, just as it is crucial for your baby’s well-being that you express your milk in a safe way, so too is it vital that you store and transport it in a way that minimizes risks for your baby.
If you’re looking for information on how to safely store and transport breast milk, then read on. If you need a little help to get you started, then check out our post on expressing breast milk.

When compared with adults, babies have very underdeveloped immune systems. As just one example, there’s an immune cell, an immunoglobulin called IgA, that’s important for fighting off the bacteria that cause gastro and babies don’t have enough of this type of cell. In fact, evena 12-month-old baby only has 15-17% of an adult level of the IgA immunoglobulin. As a result of this immune system deficiency, babies are more vulnerable than adults to a wide range of illnesses.
Perhaps the best demonstration of how easily babies can get sick is that of a baby that goes to a daycare center. You’re probably familiar with the idea that children who attend daycare frequently get sick. But did you know thatchildren that attend daycare have been reported to have 51% more episodes of infection and 134% more days of illness than children that are cared for at home!
So, because babies are so vulnerable to illnesses, it is important that we as parents and carers take reasonable precautions to prevent them from being exposed to pathogens that have the potential to cause them serious harm. One such action we can take to keep our babies safe is to ensure we safely store and transport any expressed milk we plan to feed them.
Conditions under which it is considered safe to store and transport expressed breast milk, minimize the growth of any illness-causing microorganisms that may be present in the milk or inside the container. It is especially important to minimize the growth of these microorganisms because some of the nastiest bugs like to live and grow inside milk.
If you’re expressing breast milk to donate to babies in need, chances are your milk will be used in a hospital. If this is the case, it’s important you seek advice from your donation contact about how to safely store and transport your expressed breast milk as hospital milk banks have their own specific guidelines for safe breast milk storage.
If you’re expressing and storing milk for your own baby, you may use the following guidelines, which are based on the guidelines issued by the Australian Breastfeeding Association and the National Health and Medical Research Council.
Once a feed has begun, any unused breast milk should be discarded. This is because the undrunk milk will become contaminated with microorganisms from your baby’s mouth during a feed. Safe storage conditions would minimize the growth of these microorganisms but it doesn’t take as long for the levels of harmful microorganisms to rise enough to cause illness if there are a lot of harmful microorganisms present to begin with.
If your baby is going to be fed expressed breast milk away from home, perhaps at daycare or on a day out with a non-breastfeeding parent, then you not only need to store the expressed breast milk safely, but you also need to safely transport it.
To do this, you’ll need to transport it in an insulated container that will keep it cool. This might be an insulated cool bag or box designed to transport baby bottles or it could be an insulated container designed to transport food. Whatever container you choose, it should be made from food-safe materials. To help keep the breast milk cool, you can also place frozen freezer blocks in the container.
It’s also a good idea to add an extra label to the container of milk stating exactly what it is. That way it can’t be confused with something else down the track if it doesn’t end up getting drunk. If the milk is being stored at a daycare center or somewhere similar, make sure you put your baby’s name on it too so it doesn’t get mixed up with another baby’s milk or formula.
Ideally, you should transport breast milk that has been frozen. When it gets to the destination, it should be placed immediately in a freezer if it’s still frozen. If it has begun to thaw, however, it’ll need to be stored in a fridge and used within 4 hours. Do not refreeze it.
If you need to transport freshly expressed breast milk, it’s best to store it in a fridge as soon as it arrives at the destination. It should then be used within 6-8 hours as you cannot be sure how cold it remained during transport.
