How do baby's senses develop in the tummy?


The baby's senses begin to develop from the mother's womb and gradually develop until after birth. Each of the 5 senses begins to form at different gestational ages and has its own characteristics. Some form completely from the womb, while others develop more after birth.

The tactile sense

The tactile sense develops and forms from the embryo stage of the fetus. Even before 8 weeks of pregnancy, the embryo is sensitive to touch. The first parts of the body that experience sensitivity are those that are sensitive to adults: cheeks, genital area (10 weeks), palms (11 weeks) and soles of the feet (12 weeks).

And the abdomen and buttocks begin to touch when they are 17 weeks pregnant. The face manages to feel the touch and to experience the tactile sensation when moving through the mother's womb and rubbing against his walls or sucking his finger.

Up to 32 weeks, each part of the body of the fetus is sensitive to heat, cold, pain or pressure.

Smell (smell)

The nose of the fetus develops somewhere between 11 and 15 weeks. It has long been thought that it cannot manifest the sense of smell in the mother's tummy, since it depends on air and breathing.

The nasal system consists of 4 subsystems. It is considered that the amniotic fluid that surrounds the fetus also passes through its oral or nasal cavity and triggers the sense of smell.

Babies feel and are attracted to the smell of mother's milk since birth, even though they have never experienced it. The specialists claim that this is due to the development of this feeling since the intrauterine life.

The taste

The taste buds of the fetus develop as much as those of adults from the gestational age of 13-15 weeks. Through the amniotic fluid that surrounds it in the womb, the fetus can strongly feel the taste of garlic, onion, cumin or other strong flavors in the mother's diet. It is considered that the ability to swallow the fetus develops more when it is surrounded by sweet, and less bitter or bitter tastes.

In the last trimester of pregnancy, the fetus is able to swallow more than 1 liter of amniotic fluid per day, thus making the transition to the mother's breast milk aroma or to other tastes that the pregnant woman prefers.

Newborns have an extremely well developed taste and can easily differentiate between the tastes of food. They also already have well-defined culinary preferences from the moment of birth.

Hearing sensation

The mother's womb is not a silent place for the baby to enjoy peace. The face is subject to the sounds emanating from the beats of your heart, intestinal or stomach movements and those of the blood vessels that pass through the body. In addition, he also hears your voice or those of others.

His ears begin to form and be structurally complete by the 24th week of pregnancy. But he can hear different things before their development is complete.

Up to 27 weeks, the little boy not only hears the voices from outside, but is able to recognize them after being exposed several times to them. The sounds heard are unclear, hard to decipher because they are covered with vernix (thick wax that protects the fetus's skin from amniotic fluid).

The visual sense

This is the last feeling that begins to develop in the fetus. In the intrauterine cavity his eyes remain closed for close to 26 weeks. This is necessary to allow the complete development of the retina. At this gestational age his eyes start to open and he can start and blink.

Specialists claim that with the opening of the eyes in the belly it can see. In twin pregnancy, the girls manage to see each other, touch and hold hands.

But the mother's womb remains a rather dark place. The baby's eyes can see the light, the pupils can expand and contract only starting at the age of 33 weeks and with the exposure of the mother to the sun or other sources of light.
