Re: "Biting" without teeth?
Why? Maybe she's starting to teethe and is using you to soothe her sore gums. Maybe she's trying to control the milk flow- stop it if it's too fast, stimulate it if it's too slow. Maybe she's just losing her grip as she nurses, and is clamping down to prevent herself from falling off the breast. Maybe she's done and is just fooling around at the end of the feeding.
What to do about it: treat it like biting. When she clamps, remove her from the breast. Lean back for a little bit. When she fusses again, allow her to nurse again. If she clamps you again, repeat the process. Eventually she should learn that a particular nursing trick results in the end of the feeding. Also, experiment with different nursing positions. If the problem is flow speed or losing her grip on the breast, a different position may help.
