PACKET OF LANSINOH breastmilk bags opened for awhile ( 18 months )

[Shell001]

Can i use them ? are the still sterile ? is it just the inside that is sterile ...

Hi - i had boots ones and i used the leftovers from ds1 for ds2 20 months later. these may have been wrapped differently though. There were 4 bags, with 5 b/m bags inside them so if the outer bag was open i chucked it but kept all the b/m bags from sealed bags - make any sense?

yeah mine are in one bag opened and they all fell out yesterday so im not too happy should be ok though its the milk inside thats kept sterile right ?
