25 weeks \' gestation: Fetal weight steadily increased at this time, compared with last week long over the more than 100 grams, about 570 grams, skin is very thin and there are many wrinkles, almost no subcutaneous fat, whole body covered with a thin layer of fluff, looks like a little old, but the body has more said. Fetus in fetus in the uterus of the mother has take up considerable space, began to fill the uterus. Fetal taste buds on the tongue is emerging.


Pay attention to the proliferation and differentiation of fetal brain cells rapidly, the volume increases, which marked the fetal brain development will enter a peak period. When the mother can eat brain foods such as walnuts, Sesame, peanut, providing adequate nutrition for fetal brain development.


If you gently with her hands in abdominal touching, the fetus will creep up, but you still feel the movements of the fetus. Rapidly increasing fetal neurons, neural synaptic formation, conditioning capacity-strengthening of the fetus, fingers start to hand clenched, toes and soles can be bent, still tightly closed eyelids.


26 weeks \' gestation: Fetal weight now at around 800 grams, sitting about 22 cm high. Subcutaneous fat beginning to appear, but not many, fetal still looks thin, whole body covered with a thin layer of fluff.


Fetal began to breathe at this time, of course, does not really air, fetal lungs are not yet fully.


Study finds that to touch the brain of the fetus at this time has had a reaction, and vision has also been development of the fetus, he has been able to open the eyes of. If your abdomen open with a flashlight irradiation, fetal automatically head towards the light, this shows that fetal perception has been at work.


27 weeks \' gestation: 27 weeks of fetal weight now has about 900 grams, has reached about 38 cm in length, tall about 25 cm. Many fetuses have long hair, eyes have been opened. If it is a boy, his testicles have not come down, if a girl you can already see the bumps of the labia. Fetal development of the auditory nervous system also has a full sound responses are more visible at the same time on the outside world. You can continue story for him or give him listening to music, it will make you feel calm and pleasant and fetal. When the trachea and lungs of the fetus not mature, but fetal breathing movements continued, of course, is to breathe in water rather than in the air, but that he actually can breathe in the air in the future there is indeed a very good exercise.


28 weeks \' gestation: Fetal weight was 1100-1400 grams of this month, sitting about 26 cm high, almost almost fill the entire space of uterus. His eyes can both open and closed, and has developed its own sleep cycle. It is interesting, he would even put their thumbs or fingers into his mouth to suck. Although fetal pulmonary Lobectomy is not yet fully, but if in case of premature at this time, under the premise of the fetus with some medical equipment, can breathe.


29 weeks \' gestation: Fetal weight approximately more than 1300 grams, sitting about 26-27 cm high, with the long legs, have about 43 cm in length. When the fetal subcutaneous fat has taken shape, looks a little fatter. Nail has also been very clear. At this point if there is exposure to light through the mother uterus wall came in, the fetus will open your eyes and head towards the light source, this shows that Visual development of the fetus is quite perfect.


30 weeks \' gestation: Fetal now about 1500 grams, about 44 cm long from head to foot. Boys of testes from abdominal near the kidneys, along the furrow to scrotal decline during the girl\'s clitoris is emergent, but has not been covered by labia, then wait until the final weeks of the prenatal. Fetal head is also increasing, and brain development very quickly. Almost most of the fetal sound has a reaction. Brain and nervous system has attained a certain level. Subcutaneous tissue continues to grow.


31 weeks of gestation: lungs and digestive system has basically completed the development of the fetus, slower growth in length and weight is increasing rapidly. Fetal eyes closed when opening this week, he might have been able to see the scene in the womb can also distinguish light and even tracking light. If you use a small flashlight abdominal irradiation, fetal turned to follow the light, might even lend a hand to touch.


32 weeks \' gestation: Fetal had 32 weeks, his body and limbs is continuing to grow, ultimately was commensurate with the proportion to the head. Fetal now weighing about 2000 grams of body fat under the skin of the richer, wrinkle reduction, looks more like a baby.


You will find that fetal movements have now number less than the original, action has also weakened, never as your belly tumbling as the original. Don\'t worry, as long as you can feel the fetus in creep, it shows he is very good. This is because the fetus has grown too big for the many mother uterus almost of space is filled up, his hands open. Even so, the fetus will continue to grow up, but in living longer at least 1000 grams!


33 weeks \' gestation: Fetal weight approximately 2000 grams, about 48 cm in length. Mothers in the womb of space has become very crowded, baby\'s room is much smaller. When the fetal subcutaneous fat has increased significantly earlier, wrinkle reduction, the body began to mellow. Respiratory, digestive system and development of the fetus is near maturity. Some of the fetal head had begun to drop into the pelvis.


Some fetuses have been long out of the first, and some hair rare, does not mean that the future of the former baby hair must be thick, which also does not mean that future baby hair will be sparse, so do not pay too much attention. Fetal nails has long fingers to, but normally does not exceed the fingertips.


If you are a boy, probably from the abdominal cavity drop his testes into the scrotum, but there are one or two testes of fetal birth until the day after descending into the scrotum, don\'t worry

, The vast majority of boys will be normal. If you are a girl, her labia has been a significant uplift, around close. This shows that fetal development of reproductive organs is nearly ripe.

34 weeks \' gestation: Fetal weight approximately 2,300 g now, sitting about 30 cm high. Fetus at this time should already be prepared for the birth, to head the body, that is, head gesture under head has entered the pelvis.


35 weeks \' gestation: Fetal General now has 2,500 grams, reached about 50 cm in length. He longer fat, become round. Fat under the skin of the fetus in the role after he was born to regulate body temperature. Moreover, listening of the fetus has been fully developed, if you haven\'t and you\'re talking to the fetus, that start right now. To speak with children and fetal tone should not feel that it is rather ridiculous, in fact, experimental proof of fine and high tones to better attract the attention of the fetus or infant.


36 weeks \' gestation: Fetal approximately 2,800 have weight, about 46-50 cm in length. Fetal nails this week long long, may exceed the fingertips. Two kidneys have fully, he also has to deal with some of the liver metabolism of waste.


At this point when fetal activity in your Web, his elbows and small feet and head may be clear in your abdominal emergent out, this is because the wall of the uterus and abdominal wall has become very thin. The light transmission into the uterus and therefore will have more, this makes the fetus gradually established themselves in the daily activity cycle.


Intrauterine amniotic fluid proportion of now, the increase in volume of fetal, volume of the fetus is the original tire bud now 1000 times. Maternal body weight also had reached a peak of growth, has increased about 11 to 13 kilograms. You will find the navel has become big and prominent.


37 weeks \' gestation: Fetal weight about 3,000 now grams, about 51 cm in length. Differences between the fetus is relatively large, fat, thin, but as long as the fetal body weight of more than 2,500 grams even normal. Usually b-derived from fetal body weight, than only from the mother\'s womb size fetal weight to accurately judge out some, sometimes the doctor\'s judgment and final difference between the actual weight of the fetus, and as long as the normal fetal development, not too concerned about his weight.


38 weeks \' gestation: fetus may now has 3,200 weight, also may have had about 52 cm in length. Fetal head in your swing in the pelvic cavity, pelvic skeleton around protection, safe. This also frees up more places long his little arm, leg, little butt. Many more fetal hair has grown longer, approximately 1-3 cm long, if one hair is unwanted in the parent volume, your fetus also is likely to be a small curly head. Hair is dark and many of the fetus, fetal hair some yellow, in addition to nutritional factors, genetic is one of the important reasons. Of course there are also some fetal hair is no longer a point.


Now fetal body was covered with a thin layer of fluff and most white small for fat loss, gradually disappearing, smooth skin of the fetus. These substances and other secretions are fetal swallowed with the amniotic fluid in the stomach, stored in his intestines, into black tires, he expelled from the body within a day or two after birth.



39 weeks of gestation: babies have been born is now full-term infants. Fetal weight should now has 3200-3400 g. Now in more than 3,500 grams of weight is also common in newborns, even more than 4,000 grams of high-weight neonates and fetal macrosomia also increased, with improvement of the nutritional status of people have a great relationship. General boy slightly heavier than the girls \' average weight.


Fetal now also continued to flesh, these fat reserve will contribute to the baby after the birth of thermoregulation. This little guy has completed development of body parts of organs, lungs are the last of which a mature organs, within a few hours after the baby was born he can establish normal breathing pattern.


40 weeks \' gestation: birth of most of the fetuses are in this week, but can really accurately in the expected date of birth of the baby only 5%, two weeks in advance or delayed two weeks is normal. But if two weeks late and no signs labor, it is necessary to take measures as soon as possible, such as birth to fetal oxytocin, otherwise postmaturity would be dangerous.


At this time of fetal amniotic fluid environment also changes, the original of amniotic fluid is transparent, now due to fetal body surface fluff and fetal shedding of fat, and other secretions, become some of the amniotic fluid turbidity, is milky white. Features from this gradual degradation of the placenta until the mission is complete delivery of the fetus.
