FAH co-founder Michael Gelb writes: "Breastfeeding goes back thousands of years, as in other mammalian species for good reason. At birth, the infant is nourished by breastfeeding which coordinates the respiratory system, cardiovascular system and orofacial reflexes. There is obligate nasal breathing in the human infant during the first 6 months of breast suckling achieved through an epiglottic-palatal lock. The breast is milked against a flat hard palate while nasal breathing proceeds uninterrupted."
