Question: how to know how many ounces of breastmilk?
Answer: Step 2: Divide by 6. Take your baby's weight in ounces and divide that number by 6 (132 / 6 = 22). This figure represents how many ounces of breast milk that your baby should be getting in one day. Based on the example above, the baby should be taking in about 22 ounces of breast milk in a 24-hour period.
