Q&A: Baby Keeps Biting Me While Nursing?
When you tell her "no," are you offering the breast (or other food) right afterwards? If so, try holding off on this for at least 10 to 15 minutes — even if baby gets upset. You don't want to reward her for biting. After a few days of this, most babies will take the hint that biting equals good-bye breast. (And if she laughs at your "no," try not to crack up. She needs to know you mean business.)
