Spice it up!! I don't think these findings are at all surprising, in fact they seem pretty intuitive. But why not have a little research on it?! It's just one more reason to breastfeed.
Here's an excerpt from the article from the NYT, which you can read in full here:
"The variety of flavors that you eat during pregnancy go into your blood and then into the amniotic fluid, which the baby is constantly drinking, in utero, and the flavors that you eat while nursing cross from the blood vessels that supply the mammary glands into the breast milk. So instead of restricting the maternal diet, there’s now good evidence that by eating a wide variety of healthy and tasty foods during these periods, we are actually doing our babies a major favor.
“Breast-fed babies are generally easier to feed later because they’ve had this kind of variety experience of different flavors from their very first stages of life, whereas a formula-fed baby has a uniform experience,” said Lucy Cooke, a psychologist specializing in children’s nutrition, who is a senior research associate at University College London. “The absolute key thing is repeated exposure to a variety of different flavors as soon as you can possibly manage; that is a great thing for food acceptance.” "
