freezing breastmilk?

Lexii • momma to a sweet little girl. 11/4/17 👶🏼🎀

i have about 300oz frozen (2 weeks 3days postpartum). i'm running out of room in my fridge so i freeze it all the time. i unthawed 3 bags (22oz worth) and just had to throw it away because it wasn't used in 24 hours. but now i'm told you can keep thawed milk longer. what are the rules for breastmilk in the fridge and freezer. i'm literally sick to my stomach i had to dump it all.
