2 month old destroying nipples

jrb37

Hello my 2 month old has just recently started killing me while feeding. She is clamping down super hard and turning her head all around with my nipple in her mouth. I’ve tried to gently use my arm to prevent her from turning her head but then she basically bites my nipple as hard as she can.... hoping she stays toothless until we figure this out. My nipples are so damaged they turn white between feeds and kill! What can I do?!
