I've mentioned before the calm that comes with starting the day with an empty dishwasher. What I didn't mention was that I grew up in a conservationist household, where we only ran the dishwasher every 2-3 nights or so. I had to give myself mental permission to run the dishwasher every night; that, for a short period of my life at least, starting every day with enough sippy cups and cereal spoons was worth some extra water usage. Karen agrees, specifically because she can wash the paraphernalia from her breast pump every night:
When I was pumping breastmilk, for the first few months I very carefully washed and then boiled each part of the tubing every evening. A pain in the neck, and once the pot boiled dry and we lost the tubing and the pan, and had to spend an unplanned hour or so outside b/c the house stank. You can put the tubing in the dishwasher instead, but we have a full dishwasher only a couple times a week, so I didn't even consider that. Then, I saw the light, and I started running the dishwasher every night no matter how full or empty it was, just to get the tubing clean. Yes, I can hardly believe it myself now, but it was a HUGE relief not to have to do all that washing and boiling when I was finally home from work and could actually spend some time with my dear little baby.
Another option: buy a second set of breast pump parts to keep on hand.
