Are babies able to smell before they are born?

Alan Greene, MD
Pediatrics
At about 30 weeks, babies start developing a sense of smell as their nasal cavities open and amniotic fluid begins to course through it. And, the smell of the amniotic fluid can influence a baby’s preferences after birth. Studies show babies prefer smells they learn before birth to ones they learn as newborns which is likely due to taste and smell being the dominant senses before birth, coloring the baby’s experience of the world.

When a pregnant woman smells something, there’s a good bet that those same molecules make their way across the placenta so that the baby smells it too. Plan ahead to share with your baby the tastes and smells you would love for her to love. I recommend that if there is a flavor or aroma you really want your baby to learn, aim for twelve times during the second and third trimesters.
