Breastfeeding provides many benefits to both mother and baby, however many new moms are unsure how to express and store their milk when they can not be with baby. Check out the following guidelines on how to store your breast milk safely for baby.

It’s important to know that breast milk storage guidelines are very different than what you may hear from friends about formula. Breast milk is more than simply a food or beverage… it is a living organism.
Expressing and storing breast milk to feed a baby while her mother is away is great for nursing moms, but it must be done properly to maintain the freshness of the milk.
Expressing Breast Milk
A nursing mother can express breast milk using a breast pump or she can express her milk manually. For most women using a breast pump will not only be faster, it will also yield a higher milk supply.
How do I store my breast milk?
You can freeze and/or refrigerate your pumped (or expressed) breast milk. It’s important, though, to store it in clean and sterile bottles with screw caps, hard plastic cups that have tight caps, or nursing bags (pre-sterilized bags meant for breast milk). Also make sure to put a label on each indicating when the milk was pumped (as shown on picture below). You should not add fresh milk to milk that is already frozen.

Choosing a Breast Milk Storage Container
There are many pre-sterilized breast milk storage containers on the market.
Some breast milk containers hook directly up to a breast pump and do not require transfer to another unit, for example the Avent VIA breast milk containers.
Other containers resemble ziplock bags and a woman will have to express milk into a bottle and then pour the milk into the bag. These bags may work better for breast milk that is going to be frozen than that which will be stored in a fridge.
How long can I store my breast milk?
For healthy full-term infants:
You can store it at room temperature for 4 to 8 hours (at no warmer than 77° Fahrenheit, or 25° Celsius)
You can store it in the refrigerator for up to 2 to 3 days at 32°–39° Fahrenheit (0°–3.9° Celsius)
You can store it in the freezer (be sure to leave about an inch of space at the top of the container or bottle to allow for expansion of the milk when it freezes)
- for up to 2 weeks in a freezer compartment located inside the refrigerator
- for 3 to 4 months in a freezer that’s self-contained and connected on top of or on the side of the refrigerator and is kept at 0° Fahrenheit (–18° Celsius). But be sure to store the milk in the back of the freezer, not in the door)
- for 6 to 12 months in a deep freezer that’s always 4° Fahrenheit (–20° Celsius)
My frozen breast milk changed color. Is this OK?
Breast milk that’s been frozen or refrigerated may look a little different from fresh breast milk, but that doesn’t mean it’s gone bad. It’s normal for breast milk to look slightly blue, yellow, or brown when refrigerated or frozen.
