Stop biting my nipples!

Karinne

My dear sweet pumpkin Angel doll of a baby won't stop BITING MY DAMN NIPPLES when he's nursing. My little baby shark has 5 teeth working on the 6th. I've tried taking him off when he bites- that didn't work, sternly saying no while taking him off- that doesn't work, blowing in his face- he thinks that's hilarious. Idk what to do. I don't want to stop breastfeeding but my nips are killing me! HALP! 😭😭😭
