Freezing breast milk

[dannid]

I have just started expressing and want to freeze some of my milk. A friend suggested using an ice cube tray to store the milk in, so yesterday I expressed off what I could, sterilised the tray and froze three ice cubes worth of milk. I have now expressed another few oz and need to freeze it...my question is can I just add it into the ice cube tray I have already used or would it need to be re-sterilised?! If it needs to be sterilised again, can I remove the milk that I froze yesterday and now put into a freezer bag or would that not be a safe way to store it?!

You can buy breast milk storage bags (i.e. from Tesco & other shops) that can be used to freeze breast milk. They come already pre-sterilized.
An ordinary freezer bag would presumably not be pre-sterilized, so I'd put the frozen milk in a breast milk storage bag.

Not sure about the ice cube tray thing, haven't heard this before.

i think that putting the alresdy frozen cubes into a freezer bag would be fine. I used to just express mine into breast milk freezer bags. Just make sure that the freezer door is always properly shut! I had to throw away about 80oz that id built up
