Breastfeeding was tough in the beginning but got better around 6 weeks. My son got better at latching and we nursed pain free until last week. DS is 12 weeks old and I don't know what happened but we can't seem to nurse on my left side with out terrible pain. I'm pretty sure it is just bad latch pain and not any kind of infection. It feels very similar to the pain i felt in the beginning. Has anyone experienced this? How did you fix the latch?
