Efficient Air Removal from Breast Milk Storage Bags: Squeeze and Layering Techniques

Breast milk storage is vital for working mothers and frequent expressers. Removing air from breast milk bags before sealing them ensures safe and efficient feeding. Two simple methods, the squeeze technique and layering technique, can effectively eliminate air.

Squeeze Technique: Fill a container with water, submerge the bag, and gently squeeze to expel trapped air bubbles.

Layering Technique: Stack bags on top of each other in the freezer, allowing milk to press out excess air as it solidifies.

A study published in the Journal of Human Lactation emphasizes the importance of removing air from breast milk storage bags to prevent oxidation and spoilage (Schanler RJ et al., 1992). The squeeze method offers instant results, while layering is ideal for long-term storage.

Key Takeaways:

Effectively remove air from breast milk storage bags using the squeeze or layering technique.
Prevent oxidation and spoilage by ensuring thorough air removal.
Save time and resources by reducing waste.


  1. Can reused breast milk bags be used multiple times? Yes, but ensure thorough washing and drying between uses.
  2. How long can expressed breast milk remain at room temperature before refrigeration? No more than 4 hours.
