No, microwaving is never recommended for breastmilk as it destroys valuable nutrients and vitamins in the breastmilk. Additionally, it can create dangerous "hot spots" that can burn the baby when you are feeding the milk to him or her.
Lansinoh Breastmilk Storage Bags are designed for one-time use only.
Because Lansinoh Breastmilk Storage Bags have a double zipper closure, they do not fit directly onto a pump flange but you could use them if you are willing to hold the bag onto the pump with your hand.
We recommend laying the storage bags flat to freeze them. You can put the breastmilk storage bags directly into the freezer but because plastic can sometimes stick to the freezer rack (especially if it is even slightly wet), we recommend placing the bags in some type of container or even a freezer Ziploc bag. That will also protect the bags from knocking together with other frozen items.
The thing to remember when thawing your milk is to handle it as gently as possible to preserve all the valuable nutrients. The great thing about laying the bags flat to freeze is that the thawing will take less time. Breastmilk frozen in our bags can be thawed in the refrigerator or at room temperature. You may also place the sealed bag in a bowl of warm tap water but never use extremely hot or boiling water on a stovetop. Also, do not microwave the milk to defrost as this process may destroy nutrients in your milk and create "hot spots" that would be dangerous to your baby. We recommend freezing your milk by laying the storage bag flat because it makes the thawing process quicker and easier.
According to the La Leche League International "Breastfeeding Question and Answer" book: In rare cases, some mothers who have meticulously expressed and frozen their milk for later use have discovered that all their frozen milk has turned rancid. This happens when a mother produces milk that is high in lipase, the enzyme that breaks down fat in the milk. Depending upon the level of lipase in her milk, some mothers notice this rancid smell after their milk has cooled in the refrigerator; others, notice it only after the milk has been frozen for a while.
It is suggested that every mother who is planning to freeze her milk should freeze some test batches of milk and thaw it out after a week or so to be sure it has not become rancid. If it smells rancid, she may need to scald the milk before freezing in the future to deactivate the lipase in her milk. If the mother finds that after freezing and thawing her milk that it has a rancid smell, she can prevent this from occurring in the future by heating her expressed milk to a scald (bubbling around the edges but not boiling) right after collecting it and then quickly cooling and freezing it. Scalding inactivates the lipase. Once the milk has acquired the rancid smell, however, treating the milk will not help.
