As a mother who has navigated the challenges of breastfeeding and pumping, I’ve encountered numerous questions about best practices for storing and handling breast milk. One of the most frequent queries I receive is “can you mix breast milk from different days”. With so much information out there, it can be hard to know what’s safe and what’s not. In this article, I’ll delve into this topic in detail, covering various aspects and providing expert advice and recommendations.
Mixing Frozen Breast Milk from Different Days
Many mothers freeze their breast milk to build up a stash for future use. It’s a common practice to pump, store, and freeze milk to ensure a consistent supply for your baby. However, a question arises: can you mix frozen breast milk from different days?
The short answer is yes, but with certain precautions. When mixing frozen milk, ensure that all the milk being combined is still within its safe storage period. The milk should be thawed in the refrigerator or using a safe thawing method. Once thawed, mix the milk gently and use it within 24 hours. Always label the combined milk with the date of the oldest milk to ensure you use it within the appropriate time frame. It is generally safe to mix breast milk from different pumping sessions, but follow these guidelines carefully.

What Does This Mean, Exactly?
The guideline against mixing breast milk from different days can seem confusing at first. Does it mean you can’t mix milk pumped within 24 hours, or does it refer to milk pumped on different calendar days? The distinction is crucial for mothers who pump at odd hours, such as late at night or early in the morning.
The general rule is to consider the time frame rather than strictly the calendar day. If the milk was pumped within the same 24-hour period, it is typically safe to mix. However, it’s essential to ensure that all milk is brought to the same temperature before mixing. Adding warm milk to cold milk can encourage bacterial growth, which we want to avoid. Milk from different pumping sessions/days may be combined in one container as long as these precautions are observed.

Evaluating the Recommendation
Is There Science Behind It?
Many guidelines, such as those from the Centers for Disease Control and Prevention (CDC), suggest caution when mixing breast milk from different days. The primary concern is that mothers may not treat all the mixed milk as if it was pumped at the time of the first expressed milk. This means if you mix milk pumped today with milk pumped yesterday, you should treat the combined milk as if it was all pumped yesterday and use it within that safe storage period.

These recommendations might seem overly cautious, but they aim to prevent any potential risks of bacterial contamination. While the evidence for these guidelines may not be explicitly detailed, they are based on a precautionary principle to ensure the safety of your baby.
Now, let’s tackle the specific question of mixing milk from different days:
Can You Mix Refrigerated Breast Milk from Different Days?
When it comes to refrigerated breast milk, the same principles apply. You can mix milk from different days, but ensure that the milk is at the same temperature before combining. If you have milk from yesterday and today, cool the fresh milk in the refrigerator before mixing it with the previously chilled milk.
Label the container with the date of the oldest milk and use the mixed milk within the appropriate storage period for the oldest milk. Typically, refrigerated breast milk is safe for up to four days, so use the combined milk within this time frame to ensure its safety and freshness.
Can You Mix Frozen Milk from Different Days?
Mixing frozen milk follows a similar logic to mixing refrigerated milk. Ensure that all the milk being combined is still within its safe storage period, which is usually up to six months for best quality and up to 12 months in a deep freezer. Thaw the milk in the refrigerator or using a safe method, and then mix the thawed milk gently.
Label the mixed milk with the date of the oldest milk and use it within 24 hours of thawing. This approach ensures that the milk remains safe and retains its nutritional quality for your baby.

Can You Mix Breast Milk from Different Days?
In summary, it is generally safe to mix breast milk from different days as long as you follow some basic guidelines. Ensure all milk is at the same temperature before mixing, label the combined milk with the date of the oldest milk, and use the mixed milk within the appropriate storage period for the oldest milk.
While some guidelines may seem overly cautious, they are designed to ensure the highest safety standards for your baby. By following these recommendations, you can confidently mix breast milk from different days without compromising your baby’s health.
Can You Mix Refrigerated Breast Milk with Freshly Pumped?
A common question is whether you can mix freshly pumped breast milk with refrigerated milk. The answer is yes, but you need to bring the fresh milk to the same temperature as the refrigerated milk before mixing. Placing the fresh milk in the refrigerator to cool it down to the same temperature as the stored milk prevents bacterial growth. Mixing freshly expressed breast milk with already cooled or frozen milk must be done correctly to ensure safety.
Once both are at the same temperature, you can combine them and store the mixed milk according to the date of the oldest milk. This method ensures that the milk remains safe for your baby to consume.

Combining them provides a well-rounded mix of nutrients. Just ensure proper hygiene when handling and chilling milk before mixing.
What are the rules for combining breast milk?
The CDC states that it is safe to mix refrigerated breast milk from different days if the milk is at the same temperature. Freshly expressed milk can be added to refrigerated milk, but it should be cooled first before combining.
Can I reuse breast milk baby didn’t finish?
If, after feeding your baby, you have half or a quarter of a bottle left, you can reuse it, but only if it’s done soon. The CDC recommends reusing leftover breast milk within two hours of the last feeding. If more than two hours pass, it should be discarded.
Can I mix breast milk of different temperatures?
