Hi, Carol. You asked: <<So, my question still resides in that if a woman either purchases her pump from me, or attends my pumping class so that she is informed not to wash the tubes since I address this notion in my teachings, then how often should she change the tubings? Are tubings safe to use after storage in the closet for a year, for instance, and then taking the pump out for the next baby?>> OK, we don't have actual scientific research on this. But the moms I have worked with have pulled the stuff out of storage for Baby #2 and sometimes Baby #3, and these babies haven't gotten sick (at least, not any sicker than the average breastfed baby). If there is nothing visible in the tubing, why can't we assume there is nothing more dangerous than what is in the room air? And we all know that breastmilk has great stuff in it to prevent babies from getting sick from what's in ordinary room air. I tell parents they don't need to change the tubing unless there is something visible in it.
