i am a working mother. from next month i might join my office. so at that time can i give expressed breast milk in bottle to feed my child. means bottle feeding can start now?

A. Use breast milk storage bags or clean, food-grade containers to store expressed breast milk. Freshly expressed or pumped milk can be stored: At room temperature (77°F or colder) for up to 4 hours.In the refrigerator for up to 4 days.In the freezer for about 6 months is best; up to 12 months is acceptable.
