I don't have frozen stash but my chilled bm supply seem to go exesss 3 days..can I freeze my chilled milk on day4? can I freeze them in the same storage container instead of milk bags? I'm using autumnz bottles btw. thanks!

OK thanks! I think I shall just go and get some milk bags .my supply is rather low..so I don't intend to keep freezer stash but realise recently .there have been leftovers..worried to keep chilled too long so might as well freeze...my first freezer pack! haha
