Frequently Asked Questions
q: Can I use a bottle warmer to heat frozen or refrigerated milk?
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.

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?
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?
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?
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.

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?
