Pinching and scratching at 6 months old

Nora✨
My LO is always pinching us with her nails and scratching us pretty hard.. I'm guessing it's a phase but ouch!! We play with her and we always end up all beat up lol.. oh and nursing her is painful she pinches my boob and scratches my face and chest.. I want to show her that's it's not ok but not sure how and if she even knows I'm telling her it's not ok?? Does anybody else have an abusive baby!? Any tips?
