So where did these cravings come from? I concluded it’s the baby ordering in. Prenatal takeout. Even without ever being in a restaurant, fetuses develop remarkably discerning palates, and they are not shy about demanding what they want. If they get a hankering, they just pick up the umbilical cord and call. ‘You know what would taste good right now? A cheeseburger, large fries, and a vanilla shake. And if you could, hurry it up, because I’m supposed to grow a lung in a half hour.’
