It is definitely not normal to have sore nipples during breastfeeding. Normally, nipples do not become sore when the baby is sucking. If there is pain, it may be caused by cracked nipples. It is recommended that you apply milk to your nipples after each feeding to provide protection. In addition, the incorrect sucking position of the baby can lead to cracked nipples. It is recommended to put most of the areola in the baby’s mouth when the baby opens wide to suck, so as not to cause cracked nipples. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things.
