When your baby has stopped breast feeding and gets all of his nutrition from other sources than the breast, he's actually considered weaned. Even though babies are also weaned from the bottle as well, the term weaning often refers to when a baby is stopped from breast feeding.
Many women find that they can eat whatever they may like during breast feeding. Even though it's true that some stongly favored foods can change the taste of your milk, many babies seem to enjoy the varieties of breast milk flavors. Occasionally, your baby may get cranky at the breast after you eat certain foods. If you notice this happening, simply avoid that particular food.
Jaundice is a result of buildup in the blood of the bilirubin, a yellow pigment that comes from the breakdown of older red blood cells. It's normal for the red blood cells to break down, although the bilirubin formed doesn't normally cause jaundice because the liver will metabolize it and then get rid of it in the gut.
