Great suggestions so far. I just wanted to add that when my daughter was doing this I had to start watching closely with my finger ready to break suction and unlatch her. They have to stop sucking and pull in their tongue before they can bite so if you're paying attention you can pop them off before they bite. Doing this combined with removing her from the breast and saying, "No biting, that hurts mommy" and leaving her off the breast for 30 seconds or so when she did manage to get a bite in worked for me.
