My daughter is 11 weeks old and I return to work next week. I have a lot of milk in the freezer but it's mainly from the first two weeks of her life. I had mastitis and lots of engorgement issues then. The milk is in a freezer (the fridge freezer kind) so that means it has a storage life of 3-4 months right? So I'm thinking that any milk that isn't used in the next few weeks basically needs thrown out. Is this correct? That's a lot of milk I'll throw away.
