I've typed up some of Bert's food diary.  Basically, I let him eat as much or as little as he wants and don't force him to eat anything he doesn't like.  He is not a picky eater at all and he usually eats a ton.  On top of this, I give him diluted apple juice and breastfeed him 2-3 times a day.  I like to try to give him a protein, a grain, and fruit or veg at every meal.  Certain grains like millet, buckwheat, and quinoa, are actually seeds, so they have a lot of protein & amino acids in them already.
