>>Lisa Marasco and others- How do you allow "trial periods" of the PIS? I think that's a great idea, but wondered how.<< I allow moms to try the pump out briefly in my office. We'll go through the manual, the lactina, the PNS, the NurIII, and she is able to see how each works on her and how comfortable she is with each. *Then*, she makes her selection. I have parts that I reuse---- I rinse with cold water first, then wash in hot soapy water, then boil in water in a covered pot with a little vinegar for 20 minutes, then air dry. The literature that I have on hand shows that this should be more than adequate--- I can't imagine anything living through all that and still be able to contaminate the next trial. Mothers are told in advance of my sterility procedures so that, should someone not feel comfortable, they could decline the pump trial. When you consider that doctors use metal instruments with multiple patients that have been briefly washed and then tossed in alcohol to soak...................... -Lisa Marasco, BA, LLLL, IBCLC
