The Soothing Effect of the Mother's Heart-Part 1

Just six months after a baby is born, s/he is able to react to music with a joyful reaction. Of course, the baby is able to turn to the direction of noise and is able to decipher the voices of people close to him/her and of the mother and the father. Naturally, the ears of other mammals forced to join the survival of the fittest at birth, learning to walk soon thereafter, would be much more sensitive and sharp.

However, an important fact is that the human fetus is able to listen to the emotions engulfed in such noise or voices that they are also able to react to it with an emotional response. We call the language of mother's speech to their children, "motherese", because they tend to use a specific fluctuation of pitch speech melody, and rhythm with their babies. It is completely different from the speech used to communicate with other adults. I'm sure that many adults have at one time or another witnessed such an emotional response of a baby after an emotional verbalization of the parent or adult. Therefore, the human being is able to recognize emotional content from almost the first stages of life, which is evidence of a high function of psychological processing.

The Fetus is Substantially Advanced

The human fetus's middle ear develops in about the twelfth week of pregnancy. The inner ear and the middle ear develop at different stages and the middle ear develops in about the sixteenth week of pregnancy, enabling the relay play of the middle and inner ear to take place in about the twentieth or twenty-first week of pregnancy. Subsequently, the development of the outer ear begins.

The development of the function to listen is developed in the twentieth week, which promotes the development of the fetus in terms of the experiences it is having through the sense of hearing. It is documented that the mother is able to feel the fetus react when the fetus hears a loud noise and has a bodily movement to react to that sound. Many women report that this sensation is very rewarding because that special moment affirms that she is on the way to motherhood.

When the amniotic fluid is removed from the newborn's ears after birth, s/he reacts to those sudden loud sounds of the delivery soon by spreading his/her upper and lower limbs, called the Morrow Reaction.

If the fetus's hearing is so developed, we can assume that the fetus is hearing many sounds in utero. This means that the fetus is quietly listening to the sounds of the mother's voice, mother's singing, mother's heartbeat, mother's stomach sounds, mother's conversation with others and the sounds of even the television or radio in the room.

Among all these sounds, the sound that probably has the most rhythm and strength is the mother's pumping heart rushing blood into the arteries. Thus, the fetus is preparing him/herself to enter the world, with the rhythm of these sounds from the very beginning of his/her life.
