Who didn't? Actually, I do know one person who didn't, lucky woman. EVERYONE else I know had horrible, horrible, horrible pain, including myself.
It was worst during latching on. After that, it dulled after a while to a bearable pain. I couldnt bear the thought of the latching on though, and had to grit my teeth through it.
It lasted for about a month. Grin and bear it. It gets much easier. Only determination to breastfeed got me through it. It might have been easier for our foremothers to take in the days before formula, if they couldn't afford a wet nurse - their motivation was the survival of their child!
