I want to stop breastfeeding

My son is almost 11 months old and I want to quit I feel bad because I’m like only one more month and he will be a year old I can do this on the other hand he just got his top teeth he has had his bottom two for a few months and he nibbles but nothing to bad but now he is full on biting me and I can’t get him to stop my nipples hurt so bad!! Anyone else have this problem ?

Might not look bad but it sure hurts!!!
