Every breastfeeding mum knows the drill: pump, label, freeze, repeat. But once that freezer starts overflowing, a new question pops up — should you stick with freezing, or convert some of your stash to freeze-dried powder? Here's how the two compare, side by side.

Shelf Life

Frozen breast milk is generally good for around 6–12 months in a deep freezer, depending on your storage setup. Freeze-dried breast milk, on the other hand, is shelf-stable at room temperature for up to three years. If you're building a long-term emergency stash, that's a significant difference.

Storage Space

This is the one most mums feel in their bones. A single feed of frozen milk takes up a flat bag's worth of freezer space — multiply that by months of pumping and it adds up fast. Freeze-drying removes around 87% of the water weight, so the same amount of milk shrinks down to a pouch that fits perfectly in your nappy bag.

Convenience and Travel

Frozen milk needs to stay cold, which means cooler bags, ice packs or dry ice and careful timing. Freeze-dried powder just needs a scoop and some warm water — perfect for day-care, travel, or those 3am feeds when you don't want to be juggling a defrosting bag.

If your freezer is bursting at the seams, it might be time to convert some of your stash. Our Freeze-Drying Service page walks you through the shipping kit and drop-off options, and our FAQ page answers the questions mums ask most.
