I pump and store my excess milk in the back of our refrigerator's freezer at the end of the workday. I store it in the Lasinoh breast milk storage bags.
When I would thaw a bag out, the milk had a funny "freezer" smell. So I tried putting my bags of milk in a gallon size ziplock and then putting that ziplock in another gallon size bag (essentially tripple-bagging it). This didn't help. The milk has a weird taste like baby spit-up and my toddler won't drink it. I only keep the milk in the freezer for about 3 months at a time.
My husband thinks because plastic is porous the milk might be oxidizing which would be causing it to taste bad. I don't wanna have to throw it out. I like to keep a stash for emergencies.
Is the milk spoiling? Am I storing incorrectly? Has anyone else had this issue?
