Like Becky, I sometimes tell mothers that extreme washing routines are not so necessary with human milk equipment as they would think from a lifetime of dealing with pasteurized cows milk. I don't usually suggest not washing pump parts at all in between, because sometimes even if they are not bacterially contaminated one does see dust etc sticking to the sticky surfaces. Maybe not dangerous to a healthy baby, but yucky, yes? But I do often say that a fast run under the hot tap -- swish, swish -- is plenty most of the time, with an occasional more extensive visit to soap and brushes. Since there is usually a sink nearby, the one minute rinse doesn't feel so intensive as the more substantial scrubbing. (In a pinch, when no sink is around, even a wipe with a paper towel for stickiness-diminishment is probably enough until later, I'd have thought; and in fact I myself have done this when pumping at meetings, etc.) Elisheva clinical, rather than research, based, but seems kind of OK, no? *********************************************** The LACTNET mailing list is powered by L-Soft's renowned LISTSERV(R) list management software together with L-Soft's LSMTP(TM) mailer for lightning fast mail delivery.
