How to stop the pinching?

R

My daughter is 6 months old and is EBF. We've had an awesome time breastfeeding for the most part but recently when nursing she grabs my arm and/or chest and pinches HARD! It hurts so bad and I'm covered in little bruises. I've tried giving her a toy or small stuffed animal to hold, even wrapping her arm in a blanket but she always gets her little hands on me! Any advice to help stop this? Pic to show how cute she is 😊
