So DS has two bottom teeth, two top teeth and is cutting another top tooth. All day today nursing was so painful. He wasn't biting me (which he has done on occasion before), but I could FEEL his teeth the whole time, almost like they were scraping my nipple each time he sucked. I'm hoping today was a fluke because it was pretty painful and I don't want to stop BFing because of this. Has anyone else had a similar experience and/or tips for how to handle this?
