While we were rushing out of the house this afternoon to make it to swimming on time, DS was begging for a popsicle..... When we got home this evening I found the freezer door partially ajar. About 80oz of frozen BM was in there and it is now partially thawed (most bags still have large frozen chunks in them, but others are approx 50% liquid). Do I have to throw it all out, or is it still okay? DD is almost 12 months old if that makes a difference.
