Mixing Cold and Room Temperature Breast Milk: What You Need to Know
When it comes to feeding your baby, especially with breast milk, many parents find themselves wondering about the best practices for mixing different temperatures of milk. The question of whether you can mix cold and room temperature breast milk is particularly relevant for those who pump and store milk for later use.
The Guidelines on Mixing Temperatures
According to the Centers for Disease Control and Prevention (CDC), it is generally not advised to mix freshly expressed breast milk with already chilled milk. The primary concern here is that adding warm milk to cold milk can raise the temperature of the chilled milk, creating an environment that may promote bacterial growth. This is particularly important because breast milk is a perishable product, and maintaining safe storage conditions is crucial for your baby’s health.
The American Academy of Pediatrics has also weighed in on this topic, suggesting that while it is controversial, mothers can mix warm and cold milk under certain conditions. They note that pooling milk from different pumping sessions can help even out variability in nutrients, which can be influenced by factors such as the timing of pumping and how well the breast was emptied. However, this practice should be approached with caution, ensuring that the milk being mixed is at similar temperatures to minimize the risk of bacterial growth.
Best Practices for Mixing Breast Milk
If you find yourself needing to combine breast milk from different sessions, the best practice is to cool freshly expressed milk before combining it with older, previously cooled milk. This means that if you have just pumped milk at room temperature, it should be refrigerated before you mix it with milk that has been stored in the fridge. This approach helps maintain the safety and quality of the milk.
Feeding Preferences and Baby’s Comfort
While safety is paramount, it’s also worth noting that many babies can drink breast milk straight from the fridge, at room temperature, or even slightly warmed. The temperature of the milk can affect how easily it is digested, with room temperature and warm milk generally being easier for babies to digest compared to cold milk. Therefore, while mixing cold and room temperature milk is not recommended, parents can choose to warm the milk before feeding to enhance their baby’s comfort.
In conclusion, while mixing cold and room temperature breast milk is not advisable due to safety concerns, understanding the guidelines and best practices can help ensure that your baby receives the best nutrition possible. Always prioritize safe storage and handling of breast milk to protect your little one’s health.

What is the 5 5 5 rule for breast milk?

Something I recommend to moms is the 5-5-5 rule. Try and use milk within five hours at room temperature, five days in the fridge, and by five months in the freezer.

Why is mixed feeding not recommended?

If your mixed feeding involves exchanging some breastfeeds for baby formula, then your baby will not receive as many benefits as they normally would if they were exclusively breastfed. As such, their immune system may not be as well protected from certain infections1.

Can babies drink cold breast milk?

Breast milk does not need to be warmed. It can be served room temperature or cold.

Can I mix cold and room temperature breast milk?

Combining breast milk: According to the CDC’s and AAP’s most recent statements, breast milk should not be combined at different temperatures. However, you can combine breast milk from the same day.

Why is thawed breast milk only good for 24 hours?

Bacteria can grow rapidly in thawed milk, especially if it’s kept at room temperature or if the storage conditions are not optimal. Using the milk within 24 hours minimizes the risk of bacterial growth and ensures the milk is safe for your baby.

Is 2 oz of breastmilk the same as 2 oz of formula?

Try not to compare the amount of breastmilk in a bottle to formula in a bottle because they will mostly likely be different. Breastfed babies typically eat less at a feeding because breastmilk has more nutrients per ounce, and babies digest breastmilk more fully than formula.

Can breast milk from different sessions be mixed?

As long as both milks are at the same temperature and that the mixture is used within 24 hours. If you mix freshly expressed milk, which is warm, with frozen milk you can alter the nutritional properties of the milk due to the change in temperature.

What is the 120 pumping rule?

The first 12 weeks of your breastfeeding journey requires frequent breastmilk removal, stimulating healthy milk production. Studies show moms who exclusively pump for a minimum of 120 minutes per day can make enough to feed their babies primarily breastmilk.

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.

Can you mix refrigerated breast milk with room temperature formula?

If it’s stored in the freezer, it’s good for six months. If it’s at room temperature, use it within four hours. Formula mixed with breast milk can be safely refrigerated for up to 24 hours. At room temperature, use it within two hours.
