why is it that breast milk can be stored in a freezer compartment (inside the refrigerator) for up to 2 weeks, but for up to 3 or 4 months in a self-contained freezer unit of a refrigerator, and up to 6 months in a separate deep freeze unit?

why the different durations? What is the difference in the freezing?

Because each of those types of freezers is progressively colder than the previous type.

I don't know the science behind things keeping longer with a colder freeze.

Items that are stored in a deep freeze are less likely to be exposed to temperature changes that occur when the freezer door is opened and closed repeatedly, allowing a small amount of thawing and re-freezing to occur each time. This is what causes the quality of the breast milk (or any frozen food) to deteriorate. When grocery shopping, always choose an item near the rear of the freezer shelf, instead of immediately inside the door, for the same reason.

I'd never thought of that Jolie. I'll have to start doing it! uh, not the breast milk - the frozen foods..... Considering my youngest is 16, I don't think we have any need for breast milk at my house...lol

In addition to what Jolie said about opening and closing freezer doors, self defrosting freezers will cycle on their own which means the temperature can fluctuate. For this reason, ice cream gets freezer burned after a while (when you see large ice crystals forming on top). When ice cream (or breastmilk) is first frozen, it forms tiny ice crystals. Every time it thaws a little and then re-freezes, the ice crystals get a little bigger, which decreases quality. Deep freezers are typically manual defrost which is better for long term freezer storage.

Also a colder temp (ie deep freeze) will freeze the breast milk more quickly, allowing less time for any bad micro-organisms to multiply.

i just learned something new about breast milk storage today from a parenting board...you shouldn't shake it, you should swirl it to mix it up in the bottle. Whoops! I guess I'll know better for the next one.

Slightly off subject here: I have a friend who has issues "letting go". Her only son is 40 years old and she still has some of her breast milk in the freezer. What in the h*** is she saving it for? Grandchildren? Naw, her son is married but they have decided not to have children and he had a vasectomy. Weird, eh?

breast milk can only be stored up to 6 months in a deep freezer

(only 3 - 4 months in a freezer separate from the refrigerator, and only 2 weeks in a freezer compartment of a refrigerator)

how long as this grandma been keeping hers?
