If your freezer is inside of the refrigerater, not a separate door, then the milk can be there 2 weeks. If the freezer is a separate door above or below your refrigerator, then it can be there 3 months. Make sure it is deep in the freezer, and not on the door. Make sure it is clearly dated. If you have a separate deep freeze, it can be there 6 months. Even if your milk loses some nutrients in freezing, it is still much better for your baby than artificial milk!!
