My daughter's latch looks great but I can feel her gumming my nipples. It gets so painful that I'm in tears by the end of a feed. We use a nipple shield sometimes and I've been pumping so we can supplement with bottles, but I hate it. I really wanted to be able to breastfeed her. I'm trying really hard not to give up, but it's getting so stressful. Has anyone else dealt with this before?
