Article deals with the perinatal period of development of the baby. During this period, fundamental changes occur that prepare the baby for birth.

The perinatal period is a period that begins with the eighth week of intrauterine development and ends with the first week of the baby's life.

Typically, from the eighth week of the development of the baby so becomes perfect that he feels like his mother's heart beats, she discerns the colors of her voice. Therefore, it is very important to address the child as gently as possible and with a measured voice. It is necessary to constantly gently stroke the tummy, because at least some touch, he also feels and very often responds to it in his own way, smiling or frowning at all this. The baby's lungs are still underdeveloped, but if he wants to be born, there will be no huge problems for him, because he is always helped to cope with the difficulties experienced professionals.

The perinatal period of development of the baby is characterized by its activity on the 20th ninth and the thirtieth week. He already freely moves the handles and legs, knows how to stretch and even pucker. If the baby is worried about something, it reacts to it with stronger jerks, and this should make the mother think about it.

Very quickly, the body begins to strengthen the baby's body, and by the end of the first 30 weeks he begins to save muscle mass. But all the same, certain organs are still not fully developed. The navel is still slightly placed. The boys do not yet have eggs in the scrotum, and in girls the sex lips are not completely closed. Due to the emergence of a layer of epithelial cells in the alveolar sacs, the baby's lungs are straightened and he can already fully breathe without the help of others. Mom's blood has a unique feature. Regardless of the very narrow placenta, it never enters the baby's blood and mixes with it, although nutrients, water and waste freely enter through the placenta.

Perinatal development of the fetus at 30 2nd week is flamboyant in that it is placed head down, in other words in that position, he was already prepared to be born. This posture for the performance of labor is considered correct, and is called the head presentation. But it also happens that a child can turn his buttocks down. This is already associated with certain difficulties and is considered a pathology, because it already requires special help from midwives.

30 The 3rd and 30th of the 4th week are characterized by the fact that the child is already fully prepared for his own birth. Its weight reaches about 2 kg. Hair on the head is getting thicker. If the child was born at the moment, then he would not have been prematurely born, he would have breathed already without the help of others and tremendously worried did not cause.

The perinatal period on the 30th week is characterized by the fact that the baby has already grown 100% marigolds, while they are so long that he can even scratch himself before his own birth. At the same time, fatty tissue is postponed, thanks to which the baby's shoulders get roundness and softness. Eye color in all newborns monotonous - blue. But after a certain time it changes.

30 the sixth week is justified by the fact that the person already has all forms of a real kid. Cheeks plump and smooth, the muscles of the lips are quite developed, because the child is still in the womb of the mother is actively sucking fingers. His skull is mild and at birth has a tendency to flatten a little, but there is nothing terrible in this.

And the appearance of a baby quickly approaches. He grows, as they say, "not by day, but by hour". The 30th week comes, during which the fat cells actively continue to accumulate and the fat deposition is approximately fourteen grams per day. The child constantly increases in volume and descends ever lower and lower into the hip area of ??the body of the mother. During this period, she feels that it makes her breathe easier. The uterus presses on the bladder with great force, therefore it is necessary to empty it more often.

More intensive development in the perinatal period is observed at the 30th and 30th week. Fetal weight reaches about 3 kg.

Childbirth may occur at any time. The neck of the uterus can begin to unfold, and the fruit at any time may appear to the light. Therefore, constantly need to respond to any, even the smallest configurations of the body.

So, the long-awaited fortieth week comes, pregnancy approaches its own ending stage. The fruit is ready to be born.

The newborn usually has a length of forty-eight to fifty-one centimeters and weighs about 3 and a half kilograms.

At the first breath of a baby, the lungs are filled with air, the blood is evenly enriched with oxygen. The main life support systems are completely rebuilt. The main source of nutrients is mother's milk. The body weight of the baby in the first days after birth can slightly decrease. This is justified by the fact that the body is not ready immediately to adapt to new environmental conditions.

Temperature changes also adversely affect the condition of the baby's body. But very soon the body adapts to the outside world the perinatal period ends on this.
