Before babies were born, it was thought that their senses were underdeveloped and their responses were purely random, reflexive movements. Thanks to ultrasonography and other examination methods, we know today that the baby’s five senses start to develop at the earliest stages of pregnancy, and their responses are actually quite meaningful responses.

Sight is the last sensory system to develop during life in the mother’s womb. It has been observed that the fetus is not sensitive to visual stimuli before the 25th week, and has been increasingly responding to visual stimuli such as light since this week. Eyelid movements also start in this period. The baby’s eyelids are closed until the 26th week.

Unlike sound, the uterus acts as a strong barrier to light transmission and the baby is prevented from being affected by light. Although the baby’s eyes are closed until the 26th week, they respond to a strong light source applied to the expectant mother’s abdomen. In fact, the inside of the uterus is not absolute darkness. It passes light just as it passes sounds. For this reason, the baby can easily distinguish between day and night.

It is impossible to test the visual function of an unborn baby. However, when examinations in preterm babies are examined, babies born between 28 and 34 weeks are examined, the objects of these babies are 31-32 in horizontal and vertical planes. shows that they can follow from week on. 33-34. At week, this tracking ability is the same as that of a term baby. From the 33rd week, the pupils of babies can grow or shrink by reacting to light.

Just like us, babies in the mother’s womb cannot keep their eyes open for a long time in water. Even if the baby is not sleeping, he opens and closes his eyes to protect the eyeball. Only one percent of the light outside reaches the unborn baby. However, this amount is sufficient for the unborn baby to perceive the colors and record them in memory. Especially red tones are perceived better.

This is how babies’ weaknesses against red can be explained. As a result, the fetus is not a creature with underdeveloped senses as previously thought. On the contrary, their senses begin to develop from a very early period and store information in their memory by recognizing their environment. In other words, when the baby is born, he is not an unaware, defenseless “offspring”, but has acquired various experiences, even if a little, about stimuli that may be harmful to him and is born with various memories of his fetal life. Therefore, it is beneficial to apply stimuli such as sound, light and touch to the baby in a measured way.
