Just found this....which says 2 weeks....suppose it depends if you class yours as a freezer section or ice compartment...
Breastmilk Storage Guidelines
- Full term breastmilk for healthy babies can be left at room temperature (19-26 °C) for up to 6 hours
-
- It can be stored in a refrigerator (<4 °C) for up to 72 hours
-
- If you have a single-door refrigerator with freezer section, breastmilk can be stored in the freezer for up to 2 weeks (due to continuous open/closing of freezer door) (Breastfeeding Answer Book, LLLI 2003)
-
- If you have a two-door refrigerator/freezer, breastmilk can be stored in the freezer section for 3 to 4 months (Breastfeeding Answer Book LLLI 2003)
-
- Deep freeze at a constant 0°F (-18°C) for 6 months (Lawrence and Lawrence Breastfeeding, A Guide for the Medical Profession)
-
- If you have any question or concern about stored milk, discard and do not feed it to your baby
