I breastfed my first for nine months, he's now two and I have a two day old. Hospital said my latch was fine (am now home) but both nipples are shredded and I don't know what I'm doing wrong! Do I just need to feed through the pain and wait for them to toughen up? Or do I need to get him checked for a tounge tie? I am making sure he latches with a wide mouth, chin against my breast and nipple toward the roof of his mouth.
