miu, do it after bb suck leh, then u press the lump, see at the nipple where got transparent liquid come out. The eye pauline mention mdm rokiah talk abt it, arbo last time i search the whole nipple for white dot. So now i press see where transparent liquid come out, means the outlet of the lump. Sometimes the white dot hard to find, so if u daring, do what pauline do, just pick the eye and press, sometimes if lucky or much pressing the white dot will surfaced. Hot shower is help to expand the eye or passage of the milk ducts to surface, which sometimes thru pressing, the white dot might shoot out, of cos its too small to spot it flying.
