Use a moisturizing nipple cream between feedings. Purchase a commercially prepared nipple cream containing lanolin for best results. However, if you are vegan you can find vegan creams.
Make sure the baby latches correctly every time, change positions with each feeding, offer shorter more frequent feedings, and allow nipples to air dry between feeds.
We can't do any thing. Because it will affect the baby. The mother must suffer this pain. The mother feel sometimes have pain in the nipples. DO not bother about the pain.
