This will end very quickly and soon you will be comfortable nursing. At first your breasts are not accustomed to this type of work. The nipples need some time to toughen up. If a new mother tries to nurse for a few days and gives up, these experiences may be the only ones she has. If you decide to nurse, give it at least a week before you decide to quit.
Many mothers keep nursing in spite of the pain the first few days or weeks and are glad they did.
You will probably be advised to continue your 'prenatal vitamins, drink more milk, and eat a varied, balanced diet. A nursing mother needs about 500 extra calories but is still advised to avoid empty calories-that is, foods high in calories with few nutrients. Staying on a healthy diet will help you feel better and have more energy for taking care of your baby. If you decide not to breast-feed because of the dietary requirements, think about it further. You will be healthier yourself if you maintain good eating habits.
