Pinching and scratching while breastfeeding

Carrie

My LO used to gently “massage” my boob and now she’s getting so aggressive and sqeeezing a fistful of my skin as hard as she can and scratching me. I say ouch and pull her hand off but Its not working. Any other tips? Idk what I’m gonna do when her teeth come in and she bites me 😂😩
