Nursing affects a woman's entire lifestyle. A nursing mother with baby-in-tow should eat a balanced diet with plenty of calcium. This means eating fruits and vegetables, whole-grain cereals and bread, eggs, meats or beans, milk and dairy foods like cheese. The mother needs to get enough calories-about 500 more per day than usual-and she need to drink plenty of fluids. A balanced diet that includes 5 servings of milk or dairy products each day will give you enough Calcium.
