Oh, the reason I went into detail about storage is because your storage method makes a big difference in loss of nutrients and how long you can store it for.
Freezing does take away some of the nutrient value in breast milk, but that doesn't mean that you have to avoid it altogether. I use ice cube trays to freeze milk into 1 ounce cubes. Then when the tray is full (14 cubes in the trays I use), I put the cubes in a vacuum sealed bag. I am currently using the ziploc vacuum seal bags, they work great. My little one is 7 weeks old and usually goes through about 10 ounces of milk at day care a day (he is there from 7am - 5pm). The day care returns my bags when they are empty so I can wash and reuse them. Ashiepooh got the times right though is is up to a week in the fridge, up to 6 months in normal freezer, and a year or longer in deep freezer. When milk is thawed if it has a sour smell, throw it out and grab a new bag.
i'm in england, but last i was told was not to freeze it and to store in the fridge for no more than 24 hours. you could probably get an answer from ask . com(ignore the spaces)
In the fridge for 1 week!
A normal freezer for up to 6 months
deep freeze freezer for 1 year +
it depends on what kind of freezer and what the constant temperature is.
What I was told was, if you have a deep freezer, you can store it 6-12 months. you can store up 6 months in a normal freezer, but milk should be far back in freezer as possible and definitely not stored it the door.
