Why Do Babies Smell So Good?

Babies have a distinct, sweet smell that is often described as intoxicating. But what is it that makes babies smell so good?

The Science Behind the Smell

Vernix caseosa: This is a waxy coating that covers baby’s skin at birth. It is made up of dead skin cells, sebum, and other substances. Vernix caseosa is thought to protect baby’s skin from infection and dehydration.
Sweat: Babies sweat a lot, and their sweat has a slightly sweet smell. This is because baby’s sweat contains less salt than adult sweat.
Bacteria: The bacteria that live on baby’s skin produce lactic acid, which gives baby’s skin a slightly sour smell.

How to Preserve the Smell of a Baby

The smell of a baby will naturally fade as the baby grows older. However, there are a few things you can do to preserve the smell:

Don’t bathe your baby too often. Bathing your baby too often can strip away the natural oils that give baby’s skin its sweet smell.
Use a gentle soap. When you do bathe your baby, use a gentle soap that is designed for babies.
Apply a fragrance-free lotion. After bathing your baby, apply a fragrance-free lotion to help keep baby’s skin soft and smelling good.
