Hating righty

My LO (11 weeks) all the sudden HAAAATES feeding on my right boob. It had always been her favorite, up until yesterday. She'll arch her back trying to avoid righty like it's the plague. I can't even trick her in the middle of the night when she's tired, she gets mad I'm even offering it.

She still feeds on left like normal. Diaper output is normal. I don't know what's up, I squeeze and milk comes out just fine (if that detail even matters) I've tried different positions and she would rather starve than be associated with my right boob.

Suggestions? 😭 TIA
