I feel like I'm always throwing out half drank cups of WCM. I always toss them back into the fridge if my kids don't drink the whole cup, but after a day or so, I get grossed out and toss out the milk. I feel like I (they?) must waste several cups a week. I only fill the cups like 4 oz at a time anyways. I guess they just aren't huge milk drinkers!

Do you throw away a lot of cow's milk?
