What can be more beautiful and mysteriouspregnancy? Human life, its birth is a wonderful magic of nature. And to experience it, to feel joy, to doubt and eventually to press a warm, small, such a native lump of happiness only by a woman. And when you imagine what is happening in your body and how, it becomes easier to understand the causes of malaise, anxiety goes away, mental equilibrium is established. And this is a big plus for the baby, and for the mother. Development of the fetus by months, the main stages of pregnancy - the knowledge necessary for the future mother. During 9 months of pregnancy, grandiose changes are taking place in the child's development, and, to the extent that they are timely and correct, depends on the mother, too. For the first time after learning that they are pregnant, a thousand questions are born in the head about what will happen next. And then - an ordinary miracle.

First trimester of pregnancy

First month In this period, the mosthigh rate of development. The single-celled zygote, which appeared in the process of merging the female and male sexual cells, turns into an embryo. In the first month of pregnancy, its size reaches as much as 13 millimeters. Within such a short period of four weeks, a germ appears from the microscopic cells and increases its size almost 10,000 times. Another important event in the life of the embryo in the first month of development is the onset of the formation of the circulatory system. He already has blood vessels, and blood circulates through them. At the same time, a tiny heart appears. With the help of special equipment you can hear the pulse of the embryo (about 60 beats per minute). It would seem that only one month, and your future baby already had rudiments of the brain, liver and digestive system. Still defective, but already there is an umbilical cord in the form of an umbilical cord. This is the connection between mother and baby for the whole nine months. If you consider a monthly embryo under a microscope, you can see little bumps near the head. These are the future organs of hearing, smell and vision. About who will be born, while talking early. The second month The development of the fetus does not stand still. And the second month brings him significant changes. First, its length is already 25 mm, and the weight is about 2 g. The facial section is more actively forming. In addition to sensory organs, the foundations of teeth and tongue are laid. At the same stage, limbs are formed. Become noticeable handles brushes and fingers. The legs also gradually acquire a familiar outline. You can see knee cups, ankles and feet. The appearance of the first thin layer of skin also occurs in the second month of development. The development of organs, including genital organs, is already controlled by a tiny brain. The kid's liver is occupied with the formation of blood cells, and the kidneys purify it from uric acid. The thin layer of the skin of the embryo is already sensitive to touch. The third month New month - new changes. A lot changes, for example, the length of the embryo is already 75 mm, and the mass is about 30 g. Small nails start to form. The eyes are covered for centuries, the bases of the ligaments (the voice apparatus) are laid, the upper and lower lips appear. During this period, it is possible to determine the sex of the unborn child, but there is a small percentage error. It is better to wait for a later period. The baby can already swallow and release the amniotic fluid. In the ribs and spine, connective tissue is gradually replaced by cartilaginous tissue. The fetus has the first reflexes in three months. He is able to move the legs and handles, open and close the mouth, swallow the liquid.

Second trimester of pregnancy

Fourth month The fourth month of pregnancy, andyour baby is almost 20 cm tall. The development of reflexes continues. In addition to movements with handles and legs, swallowing and sucking reflexes are formed. Noticeably increases the motor activity, as muscle tissue develops intensively. Right now my mother has the opportunity to feel the wiggling of the fetus for the first time. The placenta is almost completely formed and provides vital activity for your baby. The body is now growing faster than the head, the fingers and toes are already formed. The child is covered with soft hairs and thick grease. Hair on the head is just starting to grow. Cilia and eyebrows appear, eyes are opened. The fifth month the Kid can already open his eyes well and squint. Movements are becoming more orderly, it is rather a reaction to his condition and establishing communication with his mother. The immune system continues to form, the body of the baby is already able to produce substances to fight infections (immunoglobulin and interferon). Endocrine glands begin their work. The production of hormones promotes the metabolism in the child's body and its further growth. By the end of the fifth month, the spleen is included in the work. She is intensively beginning to produce lymphocytes and monocytes to protect the body. The quality of red blood cells also depends on the work of the spleen, its duties include sorting out red blood cells, destroying substandard ones. Even now the baby adheres to the alternate wakefulness and sleep regime. But the respiratory system is not yet fully formed. And premature birth gives very little chance of a child's survival. The sixth month The activity of growth is slightly reduced. The growth of the baby is approximately 35 centimeters, weight about 560 g. The formation of subcutaneous adipose tissue continues. At six months, vision was completely formed. Eyes open and close with eyelids, the review is not limited. Sound vibrations also become available for the baby's hearing. He listens with pleasure to the voice of his mother and pleasant melodies. The palms are compressed into fists and unclenched. Modern medicine gives a six-month-old baby a chance to survive premature birth. During this same period, the sweat glands are formed on the skin of the child. Sometimes you feel a slight periodic flinch, this indicates that your baby hiccups. The appearance of the child and his behavior at the end of six months of pregnancy fully correspond to the baby before his birth. When you undergo an ultrasound procedure, you can see how the child frowned, narrowed his eyes or opened his mouth. At your request, a doctor can take a picture of your baby for you.

Third trimester of pregnancy

Seventh month The growth of the baby is almost 40 cm, and the weight- from 1.5 to 2 with a small kg. Reflex activity is very high. The kid actively moves, performs swallowing movements, even sucks a finger. Even more noticeable are the hair on the child's head. With preterm labor, it is very likely that a successful outcome is possible. The circulatory system of the baby by the end of the seventh month of pregnancy has already acquired all the necessary cells and is able to fully deliver oxygen to all points of the body. The digestive system is prepared for the adoption of mother's milk and can provide the child with all the necessary nutrients for active growth and development. Eighth month By this time the growth of the child is already 50 cm, weight varies from 2.5 to 3 kg. Places for active activities are becoming less, as the baby has grown significantly. Now the growth of fat tissue is gaining momentum, which at birth will not allow the baby to freeze. After all, in the tummy of my mother is much warmer. The child has already taken the final position with his head down, he is preparing to be born. His heart is contracted at a frequency of 120 to 160 beats per minute. If at this time you had a cardiotocogram (CTG), then your baby's heartbeat and an increase in the tone of the uterus were recorded. With the help of these results, the state of the child and the tone of the uterus are evaluated. Lungs at the stage of development, the development of surfactants (substances that promote the spreading of the lungs at birth).

The ninth month. Waiting for a miracle

The growth of the baby stops a week beforeappearance. Growth data of the baby corresponds to 52 cm (+/- 3 cm), weight is also different - from 2.8 to 4 kg. Girls are traditionally smaller than boys, but this is not necessary, there are exceptions. Adipose tissue is actively formed. The pulse becomes more frequent. The skin changes the shade to a lighter color. With the correct presentation at the age of 38 weeks, the baby's head descends closer to the entrance to the small pelvis. The child lies bent over, pressing his head to his chest, his arms crossed on his chest, and his legs are bent in the joints and pulled to the stomach. This is the pose for advancement through the birth canal. The cranial bones of the child are very soft. This is provided by nature for easy passage through the birth canal. The fluff on the body completely disappears, the hair remains only on the head. Lubrication is maintained to facilitate the delivery process. The liver produces iron in quantities necessary to provide hematopoies for the first year of life. The reproductive system is also formed. Fingers decorated with marigolds. Meeting with your baby can come unexpectedly, so be prepared for this moment. After all, very soon you will be holding it for the first time, kissing and feeding. The Kid is also looking forward to this meeting. He will certainly recognize your voice and feel Mom's warmth. The moment of birth implies the first breath and cry. The lungs are straightened, the baby breathes on its own. A new period of your baby's life begins, now all your concern for him is with you.
