My poor nipple! 🤱🏼

My almost 1yr old has out of the blue started biting my nipple when she is done nursing. I find myself fearing the end because I’m scared she will bite and most times she does. Tonight she bit me so hard that my nipple bled and a small piece of skin was taken off. Now I’m afraid for the next nursing session because my nipple is sore and I’m afraid she’ll bite again. My only thought to make sure it doesn’t happen again is to make her stop nursing before she decides she’s done. Does anyone have any experience or suggestions? My other two children never bit while nursing.
