How do I safely store expressed breast milk?

Express directly into a pre-sterilised, BPA-free breast milk storage bag, or pour milk in using a clean funnel. Seal the bag securely (look for double-zip seals to prevent leaks), label with the date and amount expressed, and store flat in the freezer to save space and speed up thawing. Fresh milk goes in the fridge or freezer immediately; never leave it at room temperature for more than 4 hours.

How long can breast milk be stored?

NHS guidance gives clear storage limits. Freshly expressed breast milk lasts up to 4 days in the fridge at 4°C or lower. In a freezer at minus 18°C or lower, it lasts up to 6 months (and up to 12 months in a very cold deep-freeze, though quality declines after 6). Once defrosted, use within 24 hours and never refreeze. Store milk in small portions (60 to 120ml) so you only defrost what you need.

Are reusable silicone storage bags better than single-use plastic ones?

It depends what matters most to you. Single-use bags are sterile out of the pack, leak-proof, and convenient for travel or sharing with childcare. Reusable silicone pouches are eco-friendly, work out cheaper over time if you're pumping regularly, and can be sterilised between uses. Many mums use both: silicone for home pumping, single-use bags for the changing bag or freezer stash.

Can I warm breast milk straight from a storage bag?

You can gently warm a sealed storage bag by placing it in a jug of warm (not hot) water for 5 to 10 minutes, or using a bottle warmer on its lowest setting. Never microwave breast milk; it destroys nutrients and creates hot spots that can scald baby. Once warmed, swirl gently to mix (don't shake, which can damage the proteins), test the temperature on your wrist, and use within an hour.

What's the best way to transport breast milk?

Keep expressed milk in an insulated cool bag with ice packs to maintain a temperature below 4°C. For short journeys (under 4 hours), a standard cool bag with 2 ice packs is fine. For longer trips, use a hard-sided cool box with several packs. Once you reach your destination, transfer the milk to a fridge or freezer within 24 hours. Lightweight, flat-pack storage bags travel well because they pack into a smaller space than bottles.
