The easiest way to stop breastfeeding after your baby has teething is to stop nursing. Breast milk is the healthiest and most beneficial food for your baby. Stopping breastfeeding is not stopping the breastfeeding, but sucking out the milk through a breast pump and feeding it through a bottle. If the nipple is ruptured, the mother may suffer from pain during breastfeeding, which may affect the baby’s ability to drink normally, but is not good for the baby’s nutrition. Once the baby bites through the nipple after teething, breastfeeding should be stopped. Nursing patches can be applied to the ruptured nipple to facilitate the repair of the ruptured nipple, and oily substances can be smeared to reduce the rupture.
