In the process of breastfeeding, many breastfeeding mothers experience nipples being bitten by their babies. Once you find a ruptured nipple or an obvious wound, you should not continue breastfeeding for the time being, that is, the affected breast should be temporarily stopped to feed the child. When the breast is full of milk, the milk can be squeezed out and put in a bottle to feed the child. 2. Use a warm towel to warm the affected breast to promote local blood circulation and help the wound heal. The first thing you need to do is to apply vitamin E or vitamin AD to the affected area to promote wound healing. 3, underwear should be loose and comfortable and breathable to prevent local infection.
