Guide to storing and serving breast milk to help you prepare and serve healthy, nutrient-packed bottle feeds every time.
What’s the shelf life of breast milk?
Breast milk is pretty durable provided it’s sealed in a sterilised air-tight container and chilled at a consistent temperature. How long it lasts will depend on where you store it. Here’s a quick run down:
Freshly expressed/pumped milk
Room temperature – up to 4 hours
Refrigeration – up to 5 days at 39.2F (4 C) or lower
Freezer (in fridge) – up to 2 weeks
Freezer (separate compartment) – up to 6 months
Thawed, previously frozen milk
Room temperature – 1-2 hours
Refrigeration – up to 1 day (24hours)
Freezer – NEVER refreeze human milk after it has been thawed
Leftover from a Feeding (baby did not finish the bottle)
Use within 2 hours after the baby is finished feeding
The best way to avoid any confusion is to label all your bottles and containers with use by dates, and use the oldest milk first.
Sometimes you might need to transport milk, so be sure to use an insulated cool bag on those occasions.What’s the best temperature to serve breast milk?
