Hello all nursing moms! I have been nursing my 5 month old daughter problem-free from day one. But for the past couple of weeks, I have been experiencing tremendous itching/soreness at the nipple, and frequent blocked ducts. She sleeps 12-13 hours at night, with no feeding. After the first am feeding, my nipples itch so much I can hardly think straight! I keep lanolin on 24/7. Some days are better than others. What are we suddenly doing wrong? Positioning? Is it her latch? Please, any advise is greatly appreciated!
