Re: Pump is starting to hurt
Not necessarily common, but certainly not uncommon. If pumping hurts, definitely try a different flange size or at least try lubing the nipple with a drop or two of olive oil. Sometimes that can enable the nipple to slide with less friction when the tube is just marginally too small. Also, start the pump on the lowest level and only gradually turn it up.
