How do I improve the quality of my breast milk so I am giving baby the best nutrition possible?

Actually, there is no need to make any special changes to your diet. Of course, it will be best to maintain a healthy and balanced diet. This will likely make you feel better. Research has shown that the the quality of a mother’s diet has little influence on her milk (nature has made it such that breast milk will provide the required nutrients for the baby even in times of famine or disasters). Therefore, what a mother eats will mostly affect her rather than the quality of her milk. The more important things to note would be: 1) Consume sufficient calories. Listen to your body and eat enough. 2) Drink enough fluid. Again, listen to your body and drink up when you feel the need to. In terms of food to avoid, the most common advice is to avoid fishes that are high in mercury. Also, though not very common, your baby may show an obvious reaction to certain food in a mother's diet. if that happens, it will be good to eliminate that food from a mother's diet.
