I had told the doctor I give up on latching and just wanted to pump exclusively. but then later in the night when baby cries non stop and I just latch, it mysteriously didn't hurt anymore at 6 days pp.
So I'm sorry you feel that your nipples are sore and cracked and everything hurts, gi e it a rest if you want to , and know that when you are ready to try again, it will get better .
Sometimes latching is the only secret weapon we have for witching hour.
