A bite can be very painful, so prioritize healing by applying breast milk to the wound and allowing it to air dry, or using a lanolin-based ointment like Lansinoh. Refrain from feeding on that side until the wound closes to prevent further damage or infection. To prevent future bites, watch closely at the end of feeding sessions and be prepared to offer a firm, calm 'no' if it happens again, while keeping an eye out for signs of teething discomfort.
