Breastfeeding can be hard at times, especially in the early days. But remember that you are not alone. Lactation consultants can help you find ways to make breastfeeding work for you and your baby. And while many women are faced with one or more of the challenges listed here, many women do not struggle at all. Also, many women may have certain problems with one baby that they don't have with their second or third baby.
See side sub-menu for some common breastfeeding challenges and ways to handle them.
