Discard the expired milk

My hubby had been bugging me to turn off the freezer in the store room. I couldn't make up my mind because I was just so reluctant to throw the expired breast milk away. I was buying time to put them to some better use such as milk bath for my big babies or make some soaps. There were 72 bags, dated since 2012, consisting of 4-10oz each. They signified my hard work. Two weeks ago, someone who has an itchy hand (also we might not find out who he was) switched the freezer off. We did not know until the room smelled sourish. So I fixed my mind and cleared the freezer, finally. I think hubby was the happiest person on earth, he has been saying that the freezer consumed a lot of electricity. But he was very smart for not doing the job himself, he wanted me to throw them off myself, so that I couldn't put the blame on him in the future!! The milk told me nothing but how hard it was to express milk outside the office. It's not that I'm super obsessed with breastfeeding. But, those days when I was away and had to find a proper place to pump was just not easy- at the Parliament House, the Surau was too packed, I sat at a corner next to janitor's room; At some meetings/visits out of office, I humbly asked for a small place to pump; and I experienced pumping at the toilet at a renowned hotel in KL. Throughout this exercise, I came out with a conclusion that the autumz storage bag is far better than jingle jungle. All the bags that leaked were of jingle jungle, and I couldn't figure out why.
