A baby’s senses are developing even before they are born, and the sense of smell is one of the earliest to mature. Many parents wonder when their little one can recognize familiar scents, especially the smell of their mother. Understanding how and when a baby’s sense of smell develops can help you bond better and support their sensory growth.
When Does a Baby’s Sense of Smell Develop?
-
In the Womb (Around 28 Weeks Gestation):
Research shows that a baby’s olfactory system begins functioning in the third trimester. Amniotic fluid carries flavors and scents from the mother’s diet, introducing the baby to different smells even before birth. -
At Birth:
Newborns are born with a strong sense of smell. They can distinguish their mother’s breast milk from others and often turn toward familiar scents. -
First 3 Months:
Babies become more responsive to different smells and may show preferences (for example, calming down at the scent of their mother’s clothing). -
By 6 Months:
Their sense of smell becomes more refined, helping them in the transition to solid foods as they begin to explore flavors.
Why Is Smell Important for Babies?
-
Bonding with Parents – Babies recognize their mother’s scent within days of birth, strengthening emotional attachment.
-
Feeding – Smell helps newborns locate the breast for feeding.
-
Comfort and Security – Familiar scents help babies feel safe and calm.
-
Development of Taste – Smell and taste are closely connected; exposure to scents aids in accepting new foods later.
