My second DD is 8 months old, and for several weeks now my nipples have been so sore. I had terrible soreness during the newborn stage with both my girls, but I BF my oldest for 15 months and never had any pain after the initial 6-8 weeks! What could be happening? She's also waking at night again... but I know that's for another thread. It just makes nursing her that extra time at night all the more frustrating!!! Has anyone experienced this?
