The Science Behind Why Do Babies Smell So Good

Why Do Babies Smell So Good

Believe it or not, there is actually science behind the new baby smells. The fragrance comes from a combination of several factors, including the baby's skin, hair, and sweat glands. Here are a few key factors that contribute to the scent:

Vernix Caseosa

Vernix caseosa is a white, waxy substance that covers a baby's skin in the womb. It acts as a protective barrier against the amniotic fluid and helps to keep the baby's skin moisturized. When babies are born, some of the vernix may still be present on their skin, which can contribute to the new baby smell.


Newborn babies are exposed to their mother's hormones while in the womb, and these hormones can affect the scent of their skin. In particular, the hormone estrogen can make a baby's skin smell sweet and pleasant.

Sweat Glands

Newborn babies have a lot of sweat glands, which can also contribute to their scent. Their sweat glands produce a different type of sweat than adults, which can have a slightly sweet, almost milky smell.

Amniotic Fluid

The amniotic fluid that surrounds a baby in the womb can also contribute to their scent. This fluid contains a variety of different compounds that can be absorbed into a baby's skin and hair.

Why Do We Love The Smell Of Babies?

It's not just new mothers who are obsessed with the smell of their own children – many people find newborn baby odour irresistible. But why is this the case?

One theory is that our attraction to the new baby smell is rooted in our evolutionary past. In the early days of human history, our sense of smell was critical for survival.

We needed to be able to identify potential threats (such as predators) and food sources. It's possible that the newborn scent triggers a response in our brains that is associated with safety, comfort, and nurturing.

Another theory is that the new baby body odor is simply a result of positive conditioning. We associate the scent of newborn babies with positive experiences (such as holding and cuddling a baby), so our brains release feel-good chemicals (such as dopamine) in response to the scent.

The Disappearance Of The New Baby Smell

As babies grow, their bodies and hormones change, which can cause the new baby odor to fade. This is because as babies age, their sweat glands produce more adult-like sweat with a different odor than what was produced in infancy.

Some compounds from amniotic fluid may also remain on the skin after birth, but these will eventually be washed away with bathing.

The Importance Of Smell In Bonding With Your Baby

Smell is one of the most powerful senses humans possess, and it plays an important role in our ability to bond with newborn babies. It is estimated that over 80% of our emotions are influenced by smell.

This means that the scent of a newborn baby can have a profound effect on us, both emotionally and physically.

Smell plays a critical role in the bond between parents and their newborn baby. Studies have shown that newborns recognize and prefer the smell of their mother’s milk, as well as their father’s scent. This recognition begins even before birth, as newborns are exposed to amniotic fluid that contains their parents’ hormones.

The new baby smell is often described as “sweet” or “angelic” and many people find it irresistible. This scent is thought to be caused by a combination of vernix caseosa (a waxy substance that coats babies in the womb), amniotic fluid, and hormones such as estrogen.

This scent is believed to have a powerful effect on new parents, as it helps to trigger a strong emotional bond between them and their baby.

The Benefits Of Skin-To-Skin Contact

One of the best ways to connect with your newborn baby is through skin-to-skin contact. This type of physical contact helps to promote bonding and can help the baby feel secure and comforted. 

Skin-to-skin contact is especially important for newborns, as it helps to regulate their body temperature and breathing. In addition, skin-to-skin contact allows parents to share the unique scent of their baby with each other, which can further strengthen the bond between parent and child.

What If Your Baby Doesn't Smell So Good?

It is normal for babies to have a certain scent, however, there are times when a baby may not smell as pleasant. This could be due to a variety of factors such as an infection, dehydration, or even just from being in the same clothes for too long.

If you notice that your baby's smell is off, it is best to contact your pediatrician for advice on how to address the issue.
