FAQs

What moms want to know

We recommend removing excess air from the bag and double-checking to ensure it is not overfilled. When zipping close, make sure your bag is sealed all the way to the ends. Lay flat to freeze. To protect the bags from contact with other frozen items or freezer surfaces, place flat bags in a container or freezer bag.

When thawing breastmilk, please remember to handle it as gently as possible to preserve all the valuable nutrients. If time is not an issue, the frozen Breastmilk Storage Bags can be thawed in the refrigerator or at room temperature. 

Pressed for time? Try placing the frozen sealed bag in a bowl of warm tap water; please never use extremely hot or boiling water on a stovetop. DO NOT microwave frozen milk storage bags as this process may destroy nutrients in the milk and create dangerous “hot spots.”

Yes, you can pump directly into the bags with any Lansinoh pump. To pump directly into the bag with a non-Lansinoh pump, a pump-into-bag adapter is required (sold separately).
