First of all, you arent alone! I have one nipple that is larger than the other so when both of babies were wee little latching on that side was painful. It took about 2 months before they grew big enough to where it was comfortable BUT they did grow and it did get better! As far as the stabbing pain, I have had that too although, from the sound of it, not as often as you have. That also went away with time but not nearly as long. With me it seemed to be off and on for a only a few weeks and it subsided only to come back very rarely after that. Again it was only on one side. Maybe we share a crazy boob gene! :-) Anyways, I hope you find a way to stick with it. Once you get past the uncomfy crazy parts it is such a special experience. Good luck to you.
