Looking through our downstairs freezer tonight, I discovered several bags of frozen milk (16 oz maybe) from mid-October. Oops! I have an almost 1 year old who is pretty much always with me. He hasn't taken a bottle in a few months, and I don't usually give him milk in a cup. Should I toss the milk? Thaw it and assess if it's bad? I have been cooking with my freezer milk recently, so that's probably what I'd do if the consensus is that it might still be useable. Any thoughts?
