ok so my master and me have been using minni cloths pins as nipple clamps and have been pinchinh them. it still realy hurts wth the clamps but otherwise i think im losing the feeling in the tips of the nipples. is this normal? also could it aftect me making brestmilk in the futre? btw we didnt use the cloths pins for that long. probly no longer than 20 mins and have recently switched to putting them on the avola insted. however we did pinch for a very long time in the past before we knew it could be dangores.
