The Science Behind the ‘Baby Smell’: How Scents Foster Bonding Between Parents and Children

University lecturer Jaakko Timonen is fascinated by the intriguing phenomenon of the “baby smell.” Despite its mysterious origins, there are several theories about its source. Some believe it comes from chemicals secreted by the baby’s sweat glands, while others think it may be from amniotic fluid or the white paste that covers the baby’s skin at birth.

Researchers have discovered that the scent of a baby has a profound effect on people’s brains, particularly mothers. Parts of the brain associated with pleasure and reward light up when exposed to the baby’s scent, creating a sense of intoxication similar to indulging in delicious chocolate that you can’t get enough of. This explains why mothers often find their babies so comforting and irresistible.

The bond between a baby and its parents is heavily influenced by smells. Babies can recognize their mother’s milk almost immediately after birth because it reminds them of the amniotic fluid they were surrounded by in the womb. On the other hand, parents quickly learn to recognize their own unique baby’s scent as well. The sense of smell plays a crucial role in fostering emotional connections between parents and their children.

The pleasant aroma of a baby’s scent tends to diminish as the child grows older, but parents still find comfort in their older children’s scent as well. The power of scent in forming and maintaining bonds within families is an aspect of human nature that continues to be studied and explored.
