I was in the similar situation and was told by multiple people as well as lacation consults that the milk is not bad. Even after the time frame of 6 months to one year it is that the milk starts to lose nutrients vs actually going bad. As far as milk banks goes you have to give them fresh milk as they need to pasturize the milk which they can not do if it has been frozen. My daughter is 15 months and I have stopped breast feeding but she is still getting my frozen milk from the freezer and is fine. The milk is 7 months old. I have a separate freezer in the garage. I had a lot of milk (LOL) and could not just throw it away. Good luck
