Biting

Hi all, My LO is almost 8 months now and he keeps biting my nipple at every feed, I’m so scared to feed him haha. I have tried so many things like: saying ow, yelping, pushing face into boob, saying no, immediately stopping the feed and putting him down, unlatching. It doesn’t matter what I do he just laughs at me. He has even bitten my partner’s shoulder when being held. Does anyone have any other tips on what we could try? I don’t want to have to express and bottle feed.
