The long nine months separate the new life that has arisen within you from being born. And during this time, the baby does a great job in its intrauterine development, growing from a simple accumulation of several cells to a small person who can hear, see, touch, smell, taste, in general, ready to constantly receive a huge amount of new information and assimilate numerous skills. It's hard to believe, but every minute the fetus has 250 new brain cells. The process of their formation is completed by the 7th month of pregnancy, which means that even in the womb the baby has almost the entire set of brain cells, only a few areas of the brain, such as, for example, olfactory bulbs that control the sense of smell, continue to develop cells already throughout life a child. So, the intrauterine life of the fetus is of key importance for the growth and movement of brain cells, the postpartum period is the time for the formation of the main connections between them.
Even in the womb, babies acquire their first knowledge of the world ...
Intrauterine development of taste
Intrauterine development of taste begins quite early. The six-month-old fetus already has taste buds in its mouth, and it can discern the taste of the amniotic fluid that it swallows. Amniotic fluid is 98-99% water, but also contains hormones, proteins, and other nutrients. If a mother who does not use garlic in her daily diet suddenly has eaten something strongly garlic, the baby can make a grimace at the moment when she feels the taste of garlic in the amniotic fluid. In general, babies already in prenatal age have large sweet tooth and prefer sweet amniotic fluid to everything else.
Getting acquainted with the tastes present in the amniotic fluid of the mother, the child prepares for the individual taste of mother's milk. There are cases when children who were weaned from their mothers at birth and did not even know the taste of mother’s milk, ate with great pleasure the food of their own region (up to the method of making rice), although they were only familiar with the taste of water in the womb. Moreover: the child is able to associate the taste of amniotic fluid with the state of the mother. For example, if a mother drinks a cup of strong coffee, the baby’s breathing and heartbeat will become more frequent, reflecting the state of the mother’s body. And even if the next time a woman drinks coffee already without caffeine, the baby will also react by feeling the taste of coffee in the waters, since he has already learned to associate the taste of coffee with a special physiological reaction.
Intrauterine development of hearing
Hearing develops in the fetus between the ages of http://www.pregnancycalendar.ru/kalendar/15_nedelya/ and http://www.pregnancycalendar.ru/kalendar/20_nedelya/. At http://www.pregnancycalendar.ru/kalendar/16_nedelya/ the baby is able to perceive sounds, and at http://www.pregnancycalendar.ru/kalendar/26_nedelya/ it starts to respond to them. This is proved by ultrasound studies: a sharp sound from the outside can cause the baby to twitch, and a new sound made by the mother's body can lead to an increase in the heartbeat of the child.
Understanding the whole world of ambient sounds, the baby is busy in the last three months of its intrauterine development. The idea that the baby is in a warm and quiet womb is not true. In addition to dozens of sounds coming from outside, the baby is surrounded by the noise of blood (which flows through the placenta with hissing), the beating of the mother’s heart (to which he so wants to nostalgically snuggle closer after birth), the noise of gases, inhalations and exhalations of the lungs, not to mention sneezing, bunches and burps.
As the fetal hearing develops, the baby learns to recognize the sound source. We all know that a newborn turns his head towards the source of a new sound, but premature babies born after 32 weeks of pregnancy have the same ability. This ability is necessary both for communication and for survival in general.
But, of course, the mother’s voice remains the most pleasant sound in the fetal life of an infant. The kid learns to recognize it, gets used to a certain rhythm of the language, highlights all kinds of shades and tones of the mother’s voice.
The baby hears the voices of other people indistinctly, as if we were listening to a conversation in another room: we hear speech, but we cannot make out the words.
Toddlers prefer to listen to what they have already met while in the womb. For example, if a mother often during pregnancy read some kind of fairy tale to her oldest child, then the youngest after birth is likely to be especially kind to this fairy tale.
Penetrating sounds of music in the womb are attractive to the baby and play an important role in the fetal development. Music can excite the baby or, conversely, soothe. Starting from the 32nd week of pregnancy, the baby can memorize music and recognize it after birth. Listening to your favorite tune, the fetus can even move to the beat of the music! By the 38th week of pregnancy, the baby begins to distinguish musical styles.
And the last thing about music - classical music is better heard from the womb than pop. And certain types of music (for example, piano or choral) in frequency are similar to mom’s voice.
Intrauterine development of touch
There are not many “developmental toys” for the baby in the womb. The texture and shape of the umbilical cord is not the same as that of the thumb, which is so nice to suck. The umbilical cord is long, with a corrugated surface and is able to bend in different directions. Such studies are of great importance for the intrauterine development of the child's senses and brain.
Intrauterine development of vision
Already on http://www.pregnancycalendar.ru/kalendar/26_nedelya/ the eyelids of the fetus open up and he begins to blink. And after 6 weeks - to http://www.pregnancycalendar.ru/kalendar/33_nedelya/ - the baby begins to distinguish between changes in lighting. Bright light, for example, from a flashlight can penetrate the skin of the abdomen, the walls of the mother’s uterus and change the appearance of the intrauterine environment. A change in lighting is a new intrauterine experience for the baby, to which he can respond with a rapid heartbeat. Unfortunately, he "learns" how we (to distinguish colors and shapes), he will learn after birth. Even in the first weeks after birth, the baby is able to see only at a distance of 20-25 centimeters. Everything further is simply blurring before his eyes. That is why we bend reflexively to talk with the newborn, creating the distance necessary for his vision.
Intrauterine development of smell
Obviously, the baby cannot smell in the womb, as it is in the amniotic fluid. But a baby with an excellent sense of smell is born: he remembers the smell of mom, the smell of her body, the smell of her chest. That is why many neonatologists advise young mothers not to use perfumes and toilet waters, because the baby can refuse to breast due to a new pungent smell.
