Hi Noriko & all--I was hoping that you might have heard of this --at a conference I attended once, a breast massage method was alluded to but not thoroughly explained, except to say that BF mothers in Japan used it and never became engorged! It was described as "first they pull/press the breast one way and then the other" showing all four quadrants of the breast to be massaged. Do you know of such a technique and/or know where to find further info on it?? Thanks! Kathy Rubin IBCLC RN
