Double is not only a great responsibility for future parents, but also a rather difficult period of pregnancy. In order to avoid any unforeseen circumstances, it is necessary to study the pregnancy of twins (twins) for weeks.
4-8 weeks
At this time, the children are still very tiny, they just begin to form vital organs. Determination of the weight of twins for weeks can begin already from this stage, although children weigh 5 g each, or even less. From 5 weeks of pregnancy, twins can be determined with the help of ultrasound. An interesting fact is that on later terms twins on ultrasound may not be determined, because the ray of the device sees only that baby who is closer.
8-12 weeks
Twins continue to grow. The toddlers have already formed a heart system, sexual organs, fingers and toes. Surprisingly, one can even see eyelids. In addition, at 12 week the intestine is already formed, and the little ones start to swallow and suck on their own.
12-16 weeks
The development of twins by week at this time is one of the most tangible. By the end of the 16th week, kids already reach weight of up to 200 grams, and in lengths up to 17 cm. Twins can independently find their fingers with their mouths and already control the movements of the head. At this time in the pregnancy of twins, the first movements of the children begin. However, they are so insignificant that my mother can not feel them.
16-20 week
Twins are almost completely formed, and their weight reaches about 300 grams each. In addition, at this time, the babies begin to react to sounds, so you can accustom children to my father's or mother's voice, put classical music, read fairy tales or poems.
Week 20-24
The face continues to form - eyelashes and eyebrows are already visible, the shape of the spout becomes noticeable. The location of twins in the abdomen is now traditional, and the kids themselves already know about the existence of each other.
24-28 week
Development of the fetus from 24 to 28 weeks for twins is especially important, because it is at the end of the 28th week that the kids become viable. During this period, the lungs form, which means that even if the babies are born before the due date, their chances for life increase significantly.
28-32 week
Weight is close to 1.5 kg, and growth - to 40 cm. In addition, the hair continues to grow, and twins already have their own sleep cycle.
32-36 week
The weight and height of the toddlers differ little from the child in single-pregnancy. In addition, the lungs of twins develop much faster, probably by preparing themselves quickly to an independent life.
36-40 week
At pregnancy twins on 37-40 week babies are considered donorshennymi and ready to occurrence on light. Of course, the weight of twins is usually less than that of a child in normal pregnancy, but at this time it is no longer a threat to life and health.
Features of twin pregnancy
As a rule, all future mothers are interested in the question of how many weeks and how to give birth to twins . Of course, multiple pregnancy can be accompanied by some complications and result in
Nevertheless, there are a number of recommendations, which are worth listening to. So, for example, during pregnancy, twins from sex, many doctors recommend to refuse, because the body and so is experiencing great stress.
A lot of questions arise about the stagnation of pregnancy with a double. As a rule, if the fetus dies in the first trimester, then there is a high probability of a successful outcome for the second child. But if one of the babies dies in the II-III trimester, then probably the second child will die.
