Freezing breast milk properly ensures its safety and quality. Here's how to do it:
Choosing Your Containers
First, select appropriate containers. The CDC recommends using breast milk storage bags or clean, food-grade containers made of glass or plastic. https://www.cdc.gov/breastfeeding/pdf/preparation-of-breast-milk_h.pdf Many options exist, including silicone trays for portioning and reusable containers. https://www.soupercubes.com/pages/breast-milk-storage-containers Some mothers opt for glass jars or silicone bags for eco-friendly alternatives. https://www.reddit.com/r/moderatelygranolamoms/comments/193m5nc/glass_jars_or_other_nonplastic_options_for/
Portioning and Freezing
- Portion Size: Freeze breast milk in smaller amounts, ideally 2-4 ounces per container. https://www.mayoclinic.org/healthy-lifestyle/infant-and-toddler-health/in-depth/breast-milk-storage/art-20046350 This minimizes waste and makes thawing easier. Some mothers prefer even smaller portions of 2-3oz. https://www.reddit.com/r/BabyBumps/comments/1ybbd2/best_advice_ive_been_given_for_freezing_and/ Others choose half-ounce portions using reusable trays. https://www.soupercubes.com/pages/breast-milk-storage-containers
- Headspace: Leave about an inch of space at the top of the container. Breast milk expands when it freezes. [Reference needed, but this is common knowledge]
- Freezer Placement: Store frozen breast milk at the back of the freezer where the temperature remains most consistent. Avoid areas near the door or freezer walls, especially in self-defrosting freezers. https://www.medela.com/en/breastfeeding-pumping/articles/pumping-tips/how-to-store-freeze-and-thaw-breast-milk
Additional Tips
- Lay flat: Laying bags flat in the freezer helps them freeze faster and results in thinner, more easily stackable containers. https://www.reddit.com/r/BabyBumps/comments/1ybbd2/best_advice_ive_been_given_for_freezing_and/
- Labeling: Label each container with the date of pumping to ensure proper rotation.
By following these steps, you can effectively freeze breast milk for future use.
