you can store it in the fridge for 2-3 days just make sure you date the
milk also it can go in the
freezer i think for upto 6 months and it is good to use the
breast milk storage bags so you can date them also and then you can take them straight from the freezer and put the bag in the baby bottle warmer. when you buy the breast pump there should be a little book about breast feeding and everything that comes with it.
