The medela ones don’t expire if unused and store in a cool dry place, so I imagine all brands are the same
Thank you
@Bethan it was more about the bags themselves as I know they are sterile but wanted to know how long for thank you though
Milkbags themselves do not expire; they are designed to be used once and discarded. However, the milk stored in the bags has a shelf life, which depends on the storage temperature. Freshly expressed milk can be stored at room temperature (77°F or colder) for up to 4 hours, in the refrigerator for up to 4 days, and in the freezer for about 6 months is best, up to 12 months is acceptable.
