Ok, another silly q. Am bf my dd2. My right breast is fine, no pain but my left nipple is constantly soret & it really hurts when she feeds. Have checked my latching position with midwife and it is fine. Am thinking of expressing this breast every other feed to try and give it a break from dd2. Will this affect my supply? And if the prob continued, could I express permanently from my left breast whilst continuing to feed dd2 from my right?
