Milk Storage Guidelines and Tips:

Store Milk:

• Preferably, human milk should be refrigerated or chilled right after it is expressed. Acceptable guidelines for storing human milk are as follows. Store milk:

• at room temperature (66-78°F, 19-26°C) for 4 hours (ideal), up to 6 hours (acceptable) (Some sources use 8 hours)

• in a refrigerator (39°F/4°C) for 72 hours (ideal); up to 8 days (acceptable)

• in a freezer (-0.4 to -4°F, -18 to -20°C) for 3-6 months (ideal) up to 6-12 months (acceptable- if in a deep freezer)

• If baby does not finish milk at one feeding, it may be refrigerated and offered at the next feeding before it is discarded or stored at room temperature for up to 1 hour.

Thaw Milk:

• Thaw slowly in the refrigerator (this takes about 12 hours – try putting it in the fridge the night before you need it). Avoid letting milk sit out at room temperature to thaw.

• For quicker thawing, hold container under running water - start cool and gradually increase temperature.  If using a milk storage bag, may place big in lager bag to ensure no leaking occurs. 

• Previously frozen milk may be kept in the refrigerator for up to 24 hours after it has finished thawing. Do not refreeze.

Warm Milk:

• Heat water in a cup or other small container, then place frozen milk in the water to warm.

• NEVER microwave human milk or heat it directly on the stove.

IMPORTANT: The cream will rise to the top of the milk during storage. Gently swirl milk (do not shake) to mix before checking temperature and offering to baby.
