Best Answer: I usually bake my boneless, skinless chicken breasts on 350 degrees for about 25 or 30 mins covered in foil, then take the foil off and bake for 5 or 10 more mins.
That depends on how and where you store it. Under most conditions, breast milk stays fresh at room temperature (60 to 85 degrees Fahrenheit) for three to four hours. But expressed milk that has little bacteria can last for six to eight hours if room temperature remains on the cooler side.You can refrigerate breast milk for three to five days and freeze it to keep it fresh even longer. Thawed breast milk will keep in the refrigerator for up to 24 hours (but don't refreeze it).If you're traveling, you can store breast milk in an insulated cooler with ice packs for up to 24 hours. Frozen breast milk stays fresh for two weeks in a refrigerator that has a single door to the freezer and refrigerator compartments. 2  In a refrigerator that has a separate door to the freezer, frozen breast milk lasts for 3 to 6 months.
Lactation consultant: Breast milk can be kept in a cooler like this with an ice pack for up to 24 hours. So for moms who have a concern about not having refrigeration at work, if you have your cooler with your ice pack, it'll be enough to store it all day and then bring it home for the baby at night.
