Baby biting nipple - OUCH! 🤕

So it doesn’t happen all the time but my LO bites my nipple (Obviously while feeding). I’ve noticed he’ll do it on one side only (🤔) when he’s either frustrated that my let down is slow or he’s straining for a poop.

Now he’s only just shy of 9 weeks so he doesn’t know any better or that it hurts but it does - A LOT! I’m concerned that it could actually cause some damage when his teeth come through since he bites so hard! Please tell me I’m not alone here! What can I do to stop this?
