There’s something undeniably enchanting about the scent of a newborn. Even though my youngest is now over six years old, just the thought of inhaling the soft, fuzzy crown of a baby’s head sends my heart racing. The aroma is nothing short of magical—warm, inviting, and utterly delightful. It’s hard to describe, but it evokes feelings of comfort and joy that are hard to match.
On particularly tough days, I’d wager that a whiff of that newborn scent could turn my mood around in no time. It’s astonishing how powerful it is. This phenomenon makes sense, considering that smell is one of our most primal senses. Research indicates that infants can recognize their mother’s unique scent almost immediately after birth, and by just three days old, they can differentiate between their mother’s breast milk and that of others. Trust me, my baby could detect my milk from a great distance!
Fascinatingly, mothers have an incredible ability to identify their baby’s specific scent, with studies showing that around 90% can accurately recognize it. I’d bet my ability to sniff out the unmistakable aroma of my baby’s dirty diapers would also be spot on!
A groundbreaking study published in 2013 revealed that the delightful scent of a newborn has effects on our brains similar to indulging in delicious food or experiencing the high from drugs. Researchers observed thirty women—half were new mothers, and half had never given birth. The study found that smelling newborns activated the brain’s dopamine pathways associated with pleasure and reward. This surge in dopamine is similar to what one experiences when consuming tasty treats or satisfying cravings for intimacy or substances.
Johannes Frasnelli, a co-author of the study, noted the significance of their findings. He remarked that while newborns can be demanding—sleeping, feeding, and needing diaper changes—many parents still regard the experience of having a baby as profoundly rewarding. He speculated that this powerful connection to the scent of babies might serve to strengthen the bond between parents and their children. “There must be mechanisms that facilitate a strong attachment,” Frasnelli explained. “The scent of infants is likely part of this system.”
Isn’t that fascinating? All parents can resonate with this! Caring for a newborn can be incredibly taxing, and it’s understandable that biology has equipped us with some rewards to ensure we don’t throw in the towel on parenting right from the start.
Interestingly, while mothers exhibited a more robust response to the baby scent, the study also revealed that non-mothers experienced similar effects. This suggests a biological drive that encourages all individuals—regardless of parental status—to feel motivated to nurture and protect newborns. As the researchers concluded, the odor of a two-day-old infant may trigger emotions that inspire care for unfamiliar babies.
Before I became a mom, I was already captivated by that newborn scent; it played a role in my decision to embrace parenthood. Perhaps there’s an evolutionary reason behind why even non-moms experience a dopamine boost when holding someone else’s baby—maybe it’s nature’s way of encouraging us to contribute to the creation of more adorable little humans.
While I’ve decided that my baby-making days are over, if someone were to hand me a newborn today and suggest I take a deep breath of that sweet baby smell, I might just reconsider my decision. It’s that intoxicating! I do wonder, however, what I’ll do when the time comes that I can no longer have children. At that point, I’ll be counting on scientists to find a way to bottle that newborn aroma, or I’ll be eagerly awaiting my kids to provide me with some grandbabies—because a mama needs her fix!
