"Parents and health professionals need to recognize
that the benefits of breastfeeding (nutritional, immunological,
cognitive, emotional) continue as long as breastfeeding itself
does, and that there never comes a point when you can replace
breast milk with infant formula, cows' milk or any other food,
or breastfeeding with a pacifier or teddy bear, without some
costs to the child."
-- KA Dettwyler, "Beauty and the Breast" from
Breastfeeding:
Biocultural Perspectives, 1995, p. 204.
