FAQ

Frequently Asked Questions

Q: Can I use a bottle warmer to heat frozen or refrigerated milk?

A: It is not recommended to use a bottle warmer with bagged milk. Bottle warmers are intended to be used with higher grade plastic or glass bottles. They can heat the plastic of a breast milk storage bag to a dangerous temperature. When the plastic is heated too much, it can melt or become dangerous to handle and can harm your bottle warmer.

Two of the milk storage bag brands on our list are a part of a feeding system. These feeding systems come with specially designed bag warmers that will not overheat the bags designed to go with that specific system. For the twist top bag feeding systems, you can use their specific warmers without worry.

Q: Can I use a microwave to heat my milk?

A: No, you can not use a microwave to heat your milk. Microwaves do not heat food evenly. They can create hot spots that could be dangerous for your baby. Using a microwave to heat your milk could cause your storage bag to break because of overheating. This would cause you to lose whatever milk you were planning to feed your little one.  

Q: So I can’t use a bottle warmer or microwave. How do I heat my milk?

A: Most bag manufacturers recommend placing the bagged milk in warm water for heating purposes. You can do this in a variety of ways. Some caregivers prefer running hot tap water over the bag; others will warm water on the stove and place the bag in the pan as the water heats. This will allow the milk to melt gradually and usually the milk will be heated thoroughly before the water on the stove is at a full boil. You can also fill a small crockpot with water, turn it on, and then place the bagged milk inside. Make sure you remember to turn off any appliances you use to heat up your milk, so you do not cause a fire hazard in your home.  

Q: What can I do to help prevent leaks?

A: The first thing you should do to prevent any milk leakage is to inspect and bag you plan to use for defects. If your bag is defect free the next step is to ensure that it is completely opened before pouring in any milk. This will help you get an accurate measurement and allow you to pour more milk into the bag. After pumping your milk ensure that the bags seal is completely free of any milk or milk residue, you may want to wipe it with a clean paper towel before sealing the bag. Next, read your bag instruction guide. How should you store your bags; do they stand up or lay flat to freeze? You should plan to store the bags in their hard-sided container for freezing. Also, do not freeze fresh milk on top of each other, freeze them laying flat beside each other and make sure all bags are completely dry before putting them in the freezer. Finally, make sure to use your frozen milk within three months. If you follow these simple storage steps, you can rest assured that your bags should not leak during storage.  When you are heating up frozen milk, it is best to first thaw the milk in a refrigerator or a cooler with an ice pack. Make sure the milk is in a container as it thaws and that nothing else is touching the bag. These easy to follow steps will help you to thaw your milk with less worry about leaks.

Q: How long can I store breastmilk in the refrigerator?

A: Fresh breast milk can be stored in the refrigerator for up to 4 days. After four days you must freeze the milk so that it can stay fresh. Thawed milk can stay in the refrigerator no longer than 24 hours before you must dispose of it properly. Do not refreeze thawed breastmilk it is dangerous for your baby because it can contain harmful bacteria. Remember that improper storage of breast milk can harm your baby. Do not forget that it is important to throw out any milk that is older than four days in the refrigerator. Make sure that you date any milk that you store. You can use a dry erase marker on a plastic bottle or a permanent marker to date a storage bag.

Q: How long can I store breastmilk in the freezer?

A: Storing pumped breast milk in the freezer is the most common way to keep your milk fresh and safe. Your frozen breast milk should not be stored for more than six to twelve months. When you store it in a freezer make sure to place your breast milk in a hard storage container and do not lay unfrozen bags on top of each other. Make sure not to stack things on top of your breast milk and do not let the bags freeze to the sides of the freezer or other items in the freezer. You should make sure that your breast milk is stored in a way that you can use the oldest milk first, so you do not have to unnecessarily throw out your valuable milk. Also, make sure that the dates are visible and don’t forget the 6-12 in the freezer rule!

Q: How long can breast milk be stored at room temperature?

A: You may not always be able to get your freshly expressed breast milk into a refrigerator or freezer right away. If this is the case, remember that you can only store it at room temperature (77 degrees Fahrenheit) for up to four hours. This is also very important to remember when you have a freshly prepared bottle. If your baby hasn’t finished the bottle in four hours, you must dispose of the milk. Do not place used milk back in the refrigerator or freezer. It can begin to grow harmful bacteria once the germs from your baby’s mouth are introduced to the bottle nipple. The germs will enter the bottle and cause bacterial growth. For your baby’s safety, please make sure to follow the 4 hours on the counter rule.
