Your baby is in cahoots with Mother Nature.

Together, they lure you (and any other helpless adult) into feeding, touching, talking to, listening to, and bonding with the newborn members of our species. About twelve inches from target is the best distance for a newborn’s built-in binoculars to see most clearly.

You play into their hands every time you position the highly-favored roundness of your face and your eyes’ rounded irises approximately that distance from your baby’s face — an inevitable consequence of breastfeeding.

Your new infant also appreciates the easy-to-see contrast between light and dark.  That’s why you’ll notice his gaze fixed on your hairline, your eyebrows, and even your moving mouth — you are talking to him during feedings, right?
