Answer: Most common cause for nipple cracking is improper latching. My sister went through the same thing. We went to a la tation consultant and after one consultation, my sister had no pain and no cracks after that. In most Nipple cracks can easily be avoided by knowing what the best latching positions are for you and your baby. But there is still a lot shaming by even mothers and mother in law's for going to a lactation consultant. Please go to a consultant in your city. There is a very very high chance your pain can completely go away by knowing the right latching techniques for you and your baby.
