7 month old hurting while nursing

Bri

My son is 7 months old. I had lots of issues in the beginning with breastfeeding (lip/tongue tie, painful latch, shallow latch). Anyway around 6 weeks postpartum that cleared up. We’ve had no issues until now! He has two teeth on the bottom and one coming in on top. My nipples are tore up. They hurt so badly, hurts to even wear a bra. Anyway, I don’t know what to do:( I tried doing more purées and food but he’s not super interested. It’s sad but I dread him latching!

Any tips or tricks from any mommas out there?
