Question: how many ounces of breastmilk should i have frozen before returning to work?
Answer: Now let's shoot for having between 3-5 days worth of milk stored before you go back to work. Multiply 12-16 ounces by 3-5 days. If you'll be missing four feedings per day, multiply 12-16 ounces by 3-5 days, and you'll get a total of somewhere between 36 and 80 ounces.
