You know all those times when seeing a newborn makes you say, “Oh, what a sweet baby! I could just eat you right up!” Or that inclination to pop those cute little toes into your mouth, or to blow a raspberry on that roly-poly tummy? Research suggests that you do those things because babies make you subconsciously think about food. It’s the smell that does it. The scent of a newborn baby activates the area of the brain that controls food cravings, and prompts a release of the feel-good chemical dopamine. Fortunately, this hunger doesn’t drive us to literally eat our young. Instead, it gives us a craving to nurture, feed and protect those precious little dumplings.
