I think i have this right, I am trying to build up a bit of a store of ebm so iv been pumping a bit each day and putting it in a bottle in the fridge. When i have enough for a freezer bag (the medela ones) I add the bottles of ebm from the fridge together into a freezer bag and date that bag with the oldest ebm (it usually takes me two or three days to fill a freezer bag). Is it ok to do it this way?
Also am i correct that you dont need to steralize the pump and bottles? Iv just been washing in hot soapy water and then rinsing and every few days ill throw everything into the steralizer.
