My great breastfeeding nutrition book is out on loan too, it is Dr Sears "The Breastfeeding Book".
LLL suggests eating more whole foods, less chemicals/additives, less artificial sugars, less sodium. They say to eat whole grains (cereals, breads, muffins) made with whole wheat and other whole grains. Dairy products if you can include yogurts, cottage cheese, natural cheeses. Eat leaner meats like chicken and fish. As many fruits and vegetables as you can stand! :wink:
I kept taking my prenatal vitamin throughout nursing, the insurance company will continue to pay for it if you are nursing.
I would always try to prepare a snack when I could for later, when I had a free moment, but when I was nursing I was usually REALLY hungry. A half a sandwich, lots of fresh fruit, boiled eggs, a veggie plate, muffins, bagels w/cream cheese, yogurt with granola, toast with PB, etc. I didn't cook much the first weeks and we didn't have anyone bringing us foods so it was a lot of easy, snack type foods. It is recommended to get 3 "meals" and 3 "snacks" in those early weeks.
Also very important to get plenty of water. Most hospitals give you the big pitcher for water to go home with you. Fill that up several times a day. Remember caffiene dehydrates you. And things like broth soups or veggie juice can help if you don't like to drink a ton of water. I also love lemon in my water.
