Biting while nursing

Baby turned a year on Christmas eve and has recently started biting again. It’s a lot more often now too, multiple times per day.

I always take the boob away from her when she does it and wait a little while before letting her nurse again, hoping she will associate biting with not being able to nurse, but she still does it.

It’s getting really frustrating and just don’t know how else to make her stop.

She also will bite us if she is upset she can’t do something, but will also bite her hand or her toys when she is not angry.

She has 8 teeth already and I was thinking maybe she is getting ready to get more teeth?

Please, if anyone has any tips, help!
