Mixing Fresh Milk with Thawed Milk: What You Need to Know
When it comes to mixing fresh milk with thawed milk, particularly in the context of breast milk, there are important guidelines to consider to ensure safety and quality.
Understanding the Guidelines
The general consensus among health professionals is that freshly expressed milk should not be mixed with previously thawed or cooled milk. This recommendation is primarily to prevent the rewarming of already stored milk, which can compromise its safety and nutritional quality. According to the Academy of Breastfeeding Medicine, adding warm, freshly expressed milk to already cooled or frozen milk is discouraged.
However, recent updates in guidelines suggest some flexibility. For instance, it is now considered acceptable to mix freshly pumped milk with thawed milk as long as the thawed milk is used within 24 hours of being fully thawed. This means that if you plan to use the milk immediately, you can combine them, but it’s crucial to adhere to the time limit to ensure the milk remains safe for consumption.
Practical Considerations
If you decide to mix fresh and thawed milk, ensure that both types of milk are at similar temperatures. This practice helps maintain the quality of the milk and reduces the risk of bacterial growth. It’s also advisable to keep the freshly expressed milk separate from any thawed milk until you are ready to use it, as this minimizes the risk of spoilage.
In summary, while mixing fresh milk with thawed milk is possible under certain conditions, it is essential to follow the recommended guidelines to ensure the safety and nutritional integrity of the milk. Always prioritize using thawed milk within the specified time frame and maintain proper temperature management to protect your baby’s health.

Can you mix fresh breast milk with refrigerated formula?

Likewise, a refrigerated bottle of formula mixed with breast milk should be used or discarded within 24 hours. While a bottle of room temperature breast milk is good for up to 5 hours, a bottle of formula or breast milk mixed with formula should be discarded after 1 hour from the start of use.

Is it OK to add freshly pumped milk to refrigerated milk?

The AAP updated their guidelines last year stating that mixing freshly pumped to refrigerated milk is okay!

Can I mix thawed breast milk with fresh?

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. Also consider storage duration guidelines for breast milk.

Can I mix formula milk with fresh milk?

If your baby isn’t a big fan of how cow’s milk tastes, you can mix equal parts whole milk and either breast milk or prepared formula (don’t mix powdered formula with whole milk instead of water). Then, gradually decrease the ratio of breast milk/formula to whole milk.

Can thawed milk be refrigerated again?

Frozen milk which has been thawed can be kept in the refrigerator for up to 24 hours. While there is some evidence that milk thawed for a few hours may be refrozen, this results in further breakdown of milk components and loss of antimicrobial activity.

Can you mix thawed breast milk from different days?

According to Verywell Family, it is safe to combine breast milk from different pumping sessions if the milk is collected and stored under clean conditions and the baby is full-term and healthy. However, it is not recommended to combine milk that has been stored for more than 24 hours.

Can I pump into the same bottle all day?

Milk stays good for 4 hours if you leave it at room temperature after pumping. So, you can pump into the same bottle within the 4 hours timeframe. Once the 4-hour timeframe has elapsed, you can either give the milk to your baby or store it in the fridge or freezer for future meals.

How long is milk good for once thawed?

Milk thawed in the refrigerator must be used within 24 hours. Milk thawed to room temperature or warmer should ideally be used in 1 to 2 hours.

Can I combine milk from different pumping sessions?

Yes, you can mix left and right breast milk when pumping. It’s common to produce different amounts of milk from each breast, and breast milk from both breasts is the same and can be combined without any concern.

Does breast milk have to be the same temperature before mixing?

The American Academy of Pediatrics previously stated: “Mothers can mix warm milk and cold, or even consider pooling milk from 24 hours together, which may help even out variability in nutrients due to pumping time or breast emptying (which influences fat content of the milk).”
