Hi Ladies. I started using the kiinde twist pouches since i no longer have room in my fridge to store breastmilk. But i notice if i pump into the bag it does not give an adequate reading of ounces/mls. My lo currently takes 4 oz every 3-4hrs. One bag after warming is 5oz. What do you guys do with the excess milk once its warmed? Throw it out? Refrigerate for next feeding? Keep at room temperature for next feeding? Refreeze?
