How to Use Lansinoh Storage Bags for Breastfeeding?

Lansinoh® Breastmilk Storage Bags are a boon for breastfeeding mothers looking to safely store and freeze their precious milk. This article will guide you on their proper use, along with some essential storage tips and highlights.

Directions for Use of Lansinoh storage bags

  1. Begin by opening the tissue pack dispenser at the marked perforation.
  2. Tear away the plastic tab and separate the two zippers to open a storage bag.
  3. Pour breast milk into the bag.
  4. To maintain freshness and avoid freezer burn, squeeze the air out of the bag before sealing.
  5. Use the double zipper seal for an assured airtight seal. Run your fingers along the zipper to ensure complete sealing.
  6. Label the bag with the date using a ballpoint pen or pencil.

Note: Avoid felt markers as they can smear when wet.

Storage Tips

  • For optimal storage, use hard-sided plastic or glass containers with tight-fitting lids, or specialized milk bags like Lansinoh’s.
  • Don’t fill containers or bags to the brim. Leave about an inch for milk expansion during freezing.
  • Avoid disposable bottle liners for milk storage due to higher contamination risk and potential leakages.
  • Label the storage with the date and, in group daycare settings, also include your baby’s name.

Frequently Asked Questions

1. Can Lansinoh breastmilk storage bags be reused?

No. Lansinoh Breastmilk Storage Bags are intended for single use. Once used, it’s essential to discard them, as they are not designed for reuse.

2. How much milk can Lansinoh bags hold?

They can hold up to 6 ounces. Specifically, Lansinoh Breastmilk Storage Bags, 50 Count, 6 Ounce, are hygienically double-sealed and ideal for both refrigeration and freezing.

3. Can you put Lansinoh bags in boiling water?

No. When thawing, place the sealed bag in warm tap water. Do not use boiling water, microwaves, or stovetops as they may harm the milk’s nutrients or create dangerous “hot spots.”

4. Are Lansinoh breastmilk bags accurate?

It’s important to understand that no storage bag will provide completely accurate milk measurements. It’s recommended to measure milk in a bottle first for accuracy and then transfer it to a storage bag. Directly pumping into the bag might not provide the most precise measurement.
