It is not a good idea to use iodophor to disinfect the nipples. The frequent use of iodophor to disinfect the nipples can easily lead to excessive iodine intake by the baby, which can lead to abnormal thyroid function in the baby, and in severe cases can cause hyperthyroidism. If you use iodophor to disinfect your nipples, you must wash them carefully before the next breastfeeding to prevent residual iodophor. Under normal circumstances, the mother can apply a few drops of milk to the nipple after each nursing session to effectively protect the nipple, as breast milk has certain antibodies that can prevent nipple infection. In addition to this, when you are nursing your baby, you must pay attention to placing the nipple on the baby’s tongue to avoid the baby’s gums from biting into the nipple to prevent nipple cracking. If you have already cracked your nipples, you can use vitamin E ointment on your nipples to promote nipple recovery.
