My LO is a week old and I've had really sore nipples for the last 3/4 days too-so much that I've cried out in pain with each feeding. I do notice it's getting better slowly, though. With each feeding the pain is a little less. I've just been continuing to feed as I read it does get better with time, and I've also been walking around with my top raised to expose my nipples to air- that helps too. Tell her don't give up. What's she's going through is normal and it will get better. My friend also had her baby 3 wks ago and suffered the same- she said her nipples are now numb and she doesn't get any pain. So there's hope.
