Father’s Voice May Shape Baby’s Bond Before Birth — Study
New research has shown that unborn babies begin responding consistently to external sounds between 22 and 24 weeks of pregnancy, highlighting early signs of learning and bonding even before birth.

According to findings by Barbara Kisilevsky of Queen’s University, fetuses are capable of recognising and remembering voices while still in the womb. The study revealed that repeated exposure to familiar sounds—particularly a father’s voice—can influence a baby’s behaviour and emotional connection after birth.
Experts explain that this ability develops as the fetus’ auditory system matures, allowing it to detect and respond to voices and other environmental sounds. This early sensory interaction plays a role in shaping attachment and recognition patterns in newborns.
In one observed case, a routine ultrasound at 32 weeks reportedly captured an unborn baby appearing to smile in response to her father’s voice, illustrating how prenatal experiences may translate into postnatal reactions.
Researchers note that such findings reinforce the importance of early parental engagement, as consistent interaction during pregnancy may help strengthen emotional bonds between parents and their children.
The study, published through ScienceDaily and indexed on PubMed, adds to growing evidence that learning and memory begin before birth, with in-utero experiences contributing to early development and attachment.
