Ok, so it still sort of pinches, almost stings when Jack latches on. It usually eases off after a minute, if it doesn't I take him off and try again, assuming his latch is wrong. Is this normal? Or do I need to work on our latch more? Also, the evenings are often pretty rough for us, he doesn't seem satisfied with what he gets from me. He'll latch on and suck but doesn't seem to be swallowing and sometimes it's quite uncomfortable as I can feel his gums against my breast. I'm pretty sure he's not getting any milk when this happens. Am I right to take him off when this happens?
