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.
Mostly pump and will apply nipple cream. But will still try to press on and latch. It will get better slowly
You can still latch if you can tahan. Just apply nipple cream after latching.
