If you have sore, cracked nipples from breastfeeding, you know how bad nursing your baby can hurt! This might sound like an exaggeration to say it's one of the worst (physical) sensation a mom has to endure. You cringe every time baby latches, bracing for the sharp, radiating pain. You hold your breath as baby sleeps, knowing that her waking up means another painful nursing session. Even the most dedicated breastfeeding mom has had the fleeting thought that it's too hard.
