Quick answer
Yes, you can pump directly into breastmilk storage bags using a compatible adapter like the Lansinoh Adapter for Breastmilk Storage Bags. This cuts down on bottle washing and transfers.
Why pump directly into bags?
Pumping directly into storage bags eliminates the step of pouring milk from a bottle or collection container into a bag. This means fewer dishes to wash and less risk of spilling or wasting milk. It also keeps the milk in one container from pump to freezer, reducing the number of times the milk is handled.
The main trade-off is that you cannot see the volume markings on the bag as easily as on a bottle during pumping. You may need to pause and check the fill level to avoid overfilling. Also, not all pumps or bags are compatible, so an adapter is often necessary.
Step-by-step: Pumping directly into bags
- 1. Attach the adapter to your pump: Remove the bottle or collection container from your breast pump flange. Screw or snap the adapter onto the flange in its place. Ensure it is tight to avoid air leaks. Check that the adapter is the correct size for your pump flange. Most adapters fit standard 24mm or 28mm flanges.
- 2. Connect the storage bag: Open the breastmilk storage bag and slide the top edge over the adapter's opening. Press the bag's seal strip firmly against the adapter to create a leak-proof connection. Some adapters have a groove that holds the bag in place. Do not overfill the bag. Most bags hold up to 6 oz (180 ml), so stop pumping once the milk reaches the fill line.
- 3. Pump as usual: Turn on your pump and begin pumping. The milk will flow directly into the bag. Keep an eye on the fill level through the bag's clear plastic. If you need to pump more than one bag's worth, have a second bag ready. If the bag starts to tip or lean, support it with your hand or place it in a small cup or container to keep it upright.
- 4. Seal and store: When finished, carefully detach the bag from the adapter. Press the zip seal closed, removing as much air as possible. Label the bag with the date and volume, then lay it flat to freeze or place it in the refrigerator. Always use a permanent marker to label the bag before freezing—wet or frozen bags are hard to write on.
