So we recently discovered our son doesn't tolerate dairy which I have eliminated from my diet for several weeks. He also has silent reflux. But I pumped and stored milk from July to October. The breastmilk will be 6 months by next month. I want to save it for when he can tolerate dairy again at 12 months possibly. But the breastmilk has just been in the freezer not deep freezer. If it was moved to a deep freezer now would it last until 12 months? It also includes a few bags of colostrum which I don't want going to waste...any advice would be appreciated!
