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

I've read that the breastmilk a mommy produce is almost always nutritionally ideal for your baby. Studies have shown that even severely malnourished mothers produce good breastmilk, because your body "takes" nutrients from the mommy's own body to supply the baby. Take stock and assess what you eat to see what you're lacking so you can make sure that you transfer all the beneficial nutrients and vitamins to baby via breastmilk. If you don't get enough sunlight, eat more foods with vitamin D. If you don't eat animal products, consider taking in vitamin B12. Take in more good fats like omega 3 or 6 fatty acids instead of trans fats. Maintain a healthy diet, stay active and try not to be too stressed --breastfeeding is such a great gift :)
