Development of Sensory Functions In The Womb

A baby’s journey in the womb is more than just growth; it’s the quiet beginning of awareness, connection, and life itself. From as early as 8 weeks, sensory development begins to shape how your baby will connect with the outside world. Understanding this silent journey, what your baby can feel, see, hear, taste, and smell can help you feel more connected to your pregnancy and more informed about the science behind it.

Pregnancy is often seen as a waiting period for a baby to develop organs and gain strength. But behind the scenes, there's another kind of development taking place, one that lays the foundation for your baby’s emotional and cognitive life: sensory development.



Your womb is your baby’s first classroom. Let’s walk through what your little one is already experiencing, long before their first cry.


Touch: The First Sense to Arrive

Touch is the very first sense to begin forming in the womb.

  • Around 8 weeks, babies start developing their sense of touch, right on the lips and nose.
  • By 12 weeks, tiny touch receptors begin forming on your baby’s palms and soles, helping them connect with the world, even before birth.
  • By 17 weeks, sensitivity has expanded to the abdomen, laying the foundation for the sense of touch even before birth.

However, while the body begins detecting sensation early, the brain’s ability to process pain does not fully form until around 30 weeks. As your baby’s nervous system matures, they gradually become able to feel things like touch, warmth, and pressure throughout their body.

This explains why late third-trimester babies often respond to gentle pokes or shifts in maternal movement.


Sight: Babies Can See Light in the Womb

Even though the womb is dark, light does make its way through. Human skin lets in a soft, filtered glow, enough for the developing foetus to notice.

  • Around the third trimester, babies begin reacting to light patterns
  • Studies have shown they track red dot patterns shaped like faces
  • This facial preference is seen even before birth
This surprising finding suggests our love for faces may be hardwired, not just learned. It also means your baby is not in complete darkness; they are already interacting with visual cues in their own quiet way.


Sound: Recognising the Mother’s Voice

The sense of hearing develops significantly during pregnancy, and what your baby hears in utero may shape their preferences after birth.

  • Around the third trimester, your baby starts picking up on sound vibrations from the world around them.
  • Research from the 1980s found that newborns preferred their mother’s voice
  • Prenatal exposure to specific stories or songs can influence newborn responses


Taste and Smell: Flavours Pass Through to the Womb

Your baby doesn’t just hear what you say; they also get a taste of what you eat. Taste and smell are deeply interconnected, and both begin developing before birth.

  • During the third trimester, fetuses typically swallow several ounces of amniotic fluid daily as part of their development.
  • Certain flavours like carrot, garlic, vanilla, mint, and anise are passed into this fluid
  • Babies exposed to these flavours in utero show preferences for them after birth


What Does This Mean for You?

While most of your baby’s sensory growth continues after birth, these early experiences lay the groundwork for emotional bonding, food preferences, language development, and attachment.

Understanding what your baby can sense helps you shape a more enriching prenatal environment. A loving touch can be calming for both of you.

  • Talk, sing, or hum regularly to your baby
  • Expose them to calming music or consistent melodies
  • Eat a variety of healthy, flavourful foods
  • Use gentle touch or belly rubs during relaxation
The womb is not only a place for physical growth but also a space where a baby’s first sensory experiences take shape. From as early as eight weeks, the senses of touch, sight, hearing, taste, and smell begin to develop, allowing the baby to interact with their environment in subtle but meaningful ways. Understanding this early sensory development can help expectant parents foster a deeper emotional connection and provide a nurturing prenatal environment. These foundational experiences influence bonding, preferences, and cognitive growth after birth, highlighting the profound impact of the womb as a baby’s first classroom.


FAQs on Development of Sensory Functions In The Womb

  1. Can babies sense pain before birth?
    Research shows that babies likely do not feel pain until after 30 weeks, when their brain’s somatosensory system is developed enough to process such signals.
  2. Can I influence my baby’s taste preferences during pregnancy?
    Yes. Studies show that exposure to certain flavours during pregnancy can influence babies’ preferences once they start eating solids.
  3. Can my baby see light in the womb?
    Yes, although limited. Foetuses can detect changes in light intensity and even track patterns, especially in the third trimester.
  4. Do babies respond to music in utero?
    They do. Regular exposure to music may calm or stimulate them, depending on the rhythm and volume. Familiar melodies may even soothe them after birth.
  5. Does learning begin before my baby is born?
    Yes, in simple and sensory ways. From recognising your voice to forming taste memories, their brain is actively processing the world around them.
