Can You Mix Refrigerated Breast Milk from Different Days?
Refrigerated breast milk is a valuable source of nutrition for infants. However, many mothers often wonder if they can mix breast milk from different days in one storage container. The answer is yes, breast milk from different days can be mixed, but there are certain guidelines that should be followed to ensure the safety and quality of the milk.
According to the Centers for Disease Control and Prevention (CDC), freshly expressed breast milk can be stored in the refrigerator for up to four days in clean conditions. However, it's best to use or freeze the milk within three days. After four days of refrigeration, the properties in breast milk that slow the growth of bad bacteria begin to decline, and the milk should be used or thrown away [1]. When combining breast milk from different days, it's important to cool the freshly expressed milk before mixing it with already refrigerated milk [2].
It's also important to note that mixing breast milk from different days can affect the milk's nutritional content. According to Mayo Clinic, the fat content of breast milk can vary from day to day, and mixing milk from different days can result in inconsistent feeding for the baby [3]. However, if mixing breast milk is necessary, it's best to mix milk from the same temperature, and use the mixed milk within the time frame of the oldest milk used in the mix [2].
Understanding Breast Milk Storage
Breast milk is a valuable source of nutrients for infants and can be stored for later use. However, proper storage is crucial to ensure that the milk is safe to consume. In this section, we will discuss the guidelines for breast milk storage, temperature considerations, and container selection.
Storage Guidelines
According to the CDC, freshly expressed breast milk can be stored at room temperature for up to 4 hours. If the room is warm, it is best to use or store the milk within 2 hours. Breast milk can be stored in the refrigerator for up to 4 days at a temperature of 40°F (4°C) or lower. If the milk is not going to be used within 4 days, it should be frozen.
Breast milk can be stored in a freezer for up to 6 months at a temperature of 0°F (-18°C) or lower. If stored in a deep freezer, breast milk can be stored for up to 12 months. It is recommended to use breast milk within 6 months to ensure the highest quality.
Temperature Considerations
It is important to maintain a consistent temperature when storing breast milk. The refrigerator temperature should be monitored with an appliance thermometer to ensure it is at or below 40°F (4°C). The freezer temperature should be monitored with an appliance thermometer to ensure it is at or below 0°F (-18°C).
When storing breast milk in the refrigerator or freezer, it is important to place it in the back of the appliance, where the temperature is the coldest. It is also important to avoid storing breast milk in the door of the refrigerator or freezer, as the temperature can fluctuate when the door is opened and closed.

Breast milk can be stored in glass or hard plastic containers with tight-fitting lids. It is important to use containers that are specifically designed for storing breast milk. Breast milk storage bags are also a popular option, as they are convenient and take up less space in the refrigerator or freezer.
When selecting a storage container, it is important to choose one that is the appropriate size for the amount of milk being stored. It is also important to label the container with the date the milk was expressed, to ensure that it is used within the recommended time frame.
In conclusion, proper storage of breast milk is essential to ensure that it is safe for consumption. By following the guidelines for breast milk storage, temperature considerations, and container selection, parents can ensure that their baby receives the best possible nutrition.
Mixing Breast Milk from Different Days
Breast milk is a valuable source of nutrients for infants. Sometimes, a mother may have to combine breast milk from different pumping sessions to provide enough milk for her baby. But can you mix refrigerated breast milk from different days?
Safety and Quality
According to the Centers for Disease Control and Prevention (CDC), it is generally safe to mix refrigerated breast milk from different pumping sessions as long as the milk has been stored properly and is the same temperature [1]. However, it is important to follow some basic guidelines to ensure the safety and quality of the milk.
Firstly, all of the milk that is mixed should be within breast milk storage guidelines. Breast milk should be stored in clean containers with tight-fitting lids and labeled with the date and time of expression [1]. Breast milk can be stored in the refrigerator for up to 4 days [1]. If the milk is not going to be used within a few days, it should be frozen.
Secondly, all of the mixed milk should be treated as if it was pumped at the time of the first expressed milk. This means that the milk should be used or discarded within 4 days of the first expressed milk [1].
Thirdly, the milk should be the same temperature before mixing. If one batch of milk is warmer than the other, it should be cooled before mixing to prevent bacterial growth [4].
Combining Milk Procedures
To combine breast milk from different days, the fresher milk should be added to the older milk. This ensures that the older milk is used up first [2]. It is important to cool the freshly expressed milk before combining it with already refrigerated milk to prevent the temperature of the refrigerated milk from rising [3].
It is generally safe to mix breast milk from different days as long as the milk has been stored properly and is the same temperature. Following the guidelines above can ensure the safety and quality of the milk.
