By weighing the baby using the baby scale, before and after nursing and doing a little subtraction, a nursing mother can determine the number of ounces the baby nursed from the breast. Since a nursing baby is usually more efficient than any breast pump, this method is preferred to breast pumping for determining how much milk the baby may be getting. For these purposes a baby scale accurate to 15 grams or less may be rented from many breast pump rental stations.
