Development of early reflexes and feelings of the baby in the womb
What exactly does the baby feel when in the mother's tummy? It turned out, that to feel babies begin already on the third month of an intrauterine life - then its sensory system develops. At seven weeks, the fetus has its first reflexes, which are improved every day. At the ninth week a tiny child is able to perform grasping movements. It is already proved that the child in the womb feels pain: if you press on his pen or leg, he will pull it away. A growing baby begins to toss and turn inside the uterus and feel everything that surrounds it: the walls of the uterus, its movements, the umbilical cord and even the amniotic fluid.
In the womb of the fetus, the hearing develops. Moreover, there is a version that the baby, being in the mother's tummy, remembers the voices of native people, and after childbirth is able to recognize them. The entire hearing system of the child is fully formed by 5 months. Since the baby reacts to loud sounds and aggressive music, pregnant women are not advised to attend concerts with "heavy" music or other noisy activities.
The development of vision and smell also occurs in the womb, but only after birth. This is due to the fact that the child is in the womb, where there is no light, no air. But, as has already been proved, if a bright and powerful ray of light is directed to the belly of a pregnant woman, the child will begin to turn to turn away and hide from it. By the way, it turns out that "puzozhiteli" see this light in orange tones.
Surprisingly, the development of taste buds also occurs when the baby is at the mother's heart. It is known that the baby swallows a certain amount of amniotic fluid (amniotic fluid) daily. In one study, an interesting fact was revealed: after introducing glucose into the amniotic fluid, the child became more active, his swallowing movements became more frequent, as a result of which he "drank" twice as much fluid as usual.
Intrauterine development of the child occurs not only at the physiological level. Many of the character traits of a little man are formed when he is in the mother's womb.
Physiological development of the child in the womb
The first day of intrauterine development: the spermatozoon meets an egg that has recently emerged from a mature follicle and is ready for fertilization. After fertilization, a cell with 46 chromosomes is formed, which already at this stage carries absolutely all the genetic information about the new person.
From 3 to 9 day of intrauterine development: The embryo is implanted into the wall of the uterus and begins to actively develop.
From 10 to 14 day of intrauterine development: There is a subsequent, more intensive, division of cells. The embryo increases by one tenth of its size.
20th day of intrauterine development: The baby begins to form the rudiments of the nervous system.
21st day of intrauterine development: A tiny toddler becomes a real man - his heart begins to beat in his body.
From the 28th to the 40th day of intrauterine development: The embryo forms the spine and muscle tissue. If the future mother during this period falls on an ultrasound examination, then it will be able to see not only the handles and legs, but even the eye cavities and ears. The brain not only increases in volume, but also signals. They can even be fixed with a special device.
After 6 weeks, the liver produces blood cells, the brain controls the work of the heart, as well as muscle movements. A little later the child begins to form jaws with rudiments of teeth. At 8 weeks the child becomes mobile, but his movements are not yet felt by his mother. When the child turns 8 weeks old, his size is only 25 millimeters, but at the same time he looks like an adult. In addition, that the heart of the baby is beating, his stomach and kidneys also function. At the age of 10 weeks the weight of the baby is 2 grams, and it already has both external and internal genital organs. By the 13th week (the end of the first trimester of pregnancy), all the organs and systems of the body are fully formed in the baby. He is already able to bend fingers on his legs and hands, open his mouth and turn his head from side to side. The bone system becomes more durable. The child at this time has already formed a vestibular apparatus, which helps to navigate by swimming in the amniotic fluid.
The second trimester of pregnancy is marked by the formation of "details" and the improvement of the organs and systems of the baby. At 16 weeks the weight of the child reaches the weight of the average mobile phone - 150 grams. On the tiny head already grows the first hairs, and on the face - eyelashes and eyebrows. At 20 weeks, when the threshold is passed in half a pregnancy, the child becomes larger and stronger. His jerks are already well felt by his mother. And in this period the baby begins. . . hiccup. Their woman feels like a weak push that comes from within and is very unlike those that are, if the baby is pushed. Approximately to the 24th week of intrauterine development, the baby "starts"as well as fat glands. His lungs begin to "ripen."
At the beginning of the third trimester the weight of the baby, as a rule, reaches a kilogram. He begins to "fat" fat, the skin also becomes more dense. Closer to 32 weeks, when it was formed subcutaneous fat, a baby can be called plump. Every day he looks more like a newborn baby. During this period all the sense organs of the fetus are fully developed. At week 34, the child, as a rule, is head down and remains in this position even before the birth. Light crumbs during this period ripen almost completely. In 37-38 weeks is an active preparation for childbirth: the baby is gaining weight, "ripening". In the liver of the future son or daughter, iron accumulates - this will help hemopoiesis in the first year of life of the baby.
In uncomplicated pregnancy, normal physiological birth occurs on the 38-40 week. As a rule, the child at birth weighs about three kilograms, and his height is about 50-52 centimeters. After giving birth, a mother with a double zeal should take care of a new person. But do not forget that a child during a stay in the womb should also feel parental love, affection and care.
