Yesterday I brought home two days worth of pumped milk and forgot to put it away. This morning I had to dump it down the sink - 27 ounces of milk from 1.25 hours of pumping. I told myself all morning that it's nothing to get upset about, but I couldn't stop crying about it. This all made me wonder about the origins of the phrase "Don’t cry over spilt milk." The literal meaning of the phrase never made much sense to me, it seemed to be such an overreaction to a minor accident. As a breastfeeding mother it gains new meaning. If you've made that milk yourself (and felt tired and dehydrated while doing it) and spent so much time pumping it (all the while not being able to actually nurse your baby, which is far, far better than pumping), losing a little, let alone 27 ounces, is heartbreaking.
