Yes, it is generally safe to mix breast milk pumped at different times. However, it is important to ensure that all the milk is at the same temperature before mixing and to follow proper storage and handling guidelines to prevent contamination.
Breast milk is a highly nutritious and unique substance that provides numerous benefits to babies. It contains a perfect balance of nutrients, antibodies, enzymes, and hormones that help support the baby’s immune system, growth, and development. However, it is common for nursing mothers to pump breast milk at different times, especially if they are building up a supply or returning to work.
Mixing breast milk from different pumping sessions can be convenient and efficient, allowing you to combine smaller amounts into a single feeding or storage container. When doing so, it is crucial to ensure that all the milk is at the same temperature before mixing. If the milk is chilled or refrigerated, gently warming the containers in warm water or using a bottle warmer can help bring them to the same temperature.
It is worth noting that breast milk can separate when stored, with the cream rising to the top. This separation is normal and does not indicate spoilage. Simply swirl the container gently to mix the layers before combining milk from different pumping sessions.
To maintain the quality and safety of mixed breast milk, it is important to follow proper storage and handling guidelines. Here are some key points to consider:
-
Cleanliness: Wash your hands thoroughly before expressing milk and ensure all pumping equipment is clean and sanitized.
-
Storage containers: Use sterile bottles, bags, or other appropriate containers designed for storing breast milk. Avoid using regular plastic bags or containers that may not be suitable for food storage.
-
Labeling: Clearly label each container with the date and time of expression to keep track of freshness. Use the oldest milk first when feeding or combining with other milk.
-
Temperature: If you plan to mix milk from different pumping sessions, ensure all containers are at the same temperature. Mixing cold and freshly pumped milk can cause thermal stress, affecting the milk’s quality.
-
Storage guidelines: Freshly expressed breast milk can be stored at room temperature (up to 77°F or 25°C) for up to four hours, in a refrigerator (at 39°F or 4°C) for up to four days, and in a freezer (at 0°F or -18°C) for around six to twelve months, depending on the type of freezer.
-
Thawing and warming: When using frozen breast milk, it is advisable to thaw it gradually in the refrigerator or using warm water. Avoid microwaving or heating breast milk on the stove directly as it can create hot spots and destroy beneficial components.
In summary, mixing breast milk from different pumping sessions is generally safe, but it is essential to ensure all milk is at the same temperature and to follow proper storage and handling guidelines. By doing so, you can continue to provide your baby with the valuable nutrition and benefits of breast milk even when using milk expressed at different times.
As famed pediatrician Dr. Benjamin Spock once said, “If a mother can’t nurse her baby directly, the next best thing is to express her milk and have someone else give it through a sterile nipple or a finger feeder. That way, the baby still gets his mother’s milk.”
Response to your question in video format
In the YouTube video “The 411 on Combining Pumped Breastmilk! Fresh. Cold. Frozen.,” Summer discusses the importance of consistent temperature when combining expressed breast milk. She advises that warm milk should be combined with warm milk, cooled milk should be combined with cooled milk, and smaller quantities of warm milk should be added to frozen or cooled milk to avoid it cooking and breaking down in quality. Summer also suggests using milk at the same temperature when combining for best results and recommends storing milk in smaller amounts for convenience as babies usually consume smaller volumes at a time.
Some more answers to your question
Can I mix freshly expressed breast milk with older breast milk? Mixing freshly expressed breast milk with already cooled or frozen milk is not advised because it can rewarm the older stored milk. It is best to cool freshly expressed milk before combining it with older, previously cooled or frozen milk.
If you pump, or hand express, your breast milk at different times during the day, you may be wondering if you can combine the breast milk from different collections into one storage container. Well, if you follow the proper guidelines, you can.
You can even combine breastmilk from pumping sessions that you did on different days. In this case, you will only have the option of adding fresh milk that you pumped today, such as refrigerated or frozen milk that you pumped in a previous day and stored it properly.
Can you mix milk from the different sides of the same pumping session? Yes, there are no issues with this. Just pour from one bottle or bag into the other, and store. Label the milk with the day you pumped it, and use it within the breast milk storage guidelines. Some people use their breast shield as a funnel when mixing milk.
Yes, it’s okay to combine breast milk from different pumping sessions, as long as you cool the milk to the same temperature before mixing them together. Label the container with the age of the oldest milk and store it accordingly.
Yes. You can mix breastmilk from different days as long as both types of milk are not altered.
Personally, I’ve combined milk from different days many times. I assumed this was safe based on what I’d read on Kellymom when my first baby was brand new: Milk from different pumping sessions/days may be combined in one container – use the date of the first milk expressed. It’s a little unclear what the VeryWell article means, exactly.
Yes. But you have to use the milk from the earliest time. Say you pumped yesterday and today and mixed those milks together in a bottle. You’ll have to use that bottle on the 4th day and time of pump from yesterday and not this morning.

Can I mix breastmilk from different pumping sessions?
You can combine it! You can combine individual pump sessions from different times or days together, or pool all of your milk over a 24 hour+ period. Pooling breastmilk is an easy and safe way to combine milk from different pump sessions over a day or two!
Is there a difference between milk pumped at different times?
Response to this: Research backs this up: Breast milk pumped in the morning has more cortisol in it than milk that’s pumped at night, whereas milk made at night contains higher levels of both melatonin and tryptophan, which are helpful in inducing sleep.
Can I pump into the same bottle all day?
The response is: Safety is priority number one, of course, but convenience isn’t far behind which leads to the question: Can you pump breast milk into the same bottle all day? “[You] can absolutely keep adding to the same bottle within that day’s time,” says Ashley Georgakapoulos, Motif Medical’s lactation director.
How long should you pump for?
Response: 15-20 minutes
A pumping session will take 15-20 minutes ideally pumping both breasts at the same time. Full milk production is about 25-35 oz. per 24 hours.
Can you mix milk between pumping sessions?
Yes, there are no issues with this. Just pour from one bottle or bag into the other, and store. Label the milk with the day you pumped it, and use it within the breast milk storage guidelines. Some people use their breast shield as a funnel when mixing milk. Can you mix milk across pumping sessions? Yes, you can. You just want to do the following:
Should I mix breast milk on the same day?
Combining the breast milk from different expressions on the same day can be convenient, especially if you’re only getting a small amount of breast milk at each session. Filling up one container instead of having a small amount in many containers just makes sense. It certainly makes it easier to store, transport, and ship your breast milk.
Can you put pumped breast milk into a bottle?
Response: In these situations, you should follow the guidelines for milk collection and storage given to you by the hospital or milk bank staff. You can add freshly pumped breast milk directly into a bottle of room temperature breast milk as long as the previously collected room temperature breast milk has not expired.
Can you mix cooled breast milk with frozen milk?
The reply will be: Mixing freshly expressed breast milk with already cooled or frozen milk is not advised because it can rewarm the older stored milk. It is best to cool freshly expressed milk before combining it with older, previously cooled or frozen milk. It is also important to consider storage duration guidelines for breast milk.
