... can be starving for food and that can impact the brain of the fetus and cause malformations. Smoking or drinking during pregnancy can form defects in the fetus and cause it to be The fetus is growing in size and has been training for his entrance into the real world. He has been moving around for quite awhile, since about the eighth week. When the fetus moves inside the uterus he is not just playing he is helping to build muscle and strengthen his bones at the same time. At this time the fetus is also starting to run out of room in the uterus. Now the fetus can't do somersaults like it used to earlier in development.
Sometimes the fetus can get hiccups, the mother feels these as small jerks. During the eighth month after the LMP the fetus has double his weight and now weighs about five and a half pounds. The brain and central nervous system has developed far enough that if the fetus was to be born now he would have a good chance of surviving. The fetus is often checked by a doctor to see if he is in the right position, head The ninth month after the LMP is when the fetus puts on a lot of weight. "The majority of fetal weight gain occurs in the third trimester"(Goliers Encyclopedia Inc.,1997,CD-ROM). Most of the lanugo has disappeared by now and is swallowed by the fetus. This collects at the bottom of the bowel.
It forms a greenish-black ooze called meconium. The baby will pass this through as his first During the first trimester the mother can and will experience vomiting and nausea, also called morning sickness. These symptoms usually occur after about eight weeks after the LMP. The mother will experience increased urination due to the pressure on the bladder. "Breast soreness or tingling often occurs do to the hormonal stimulation"(Software Toolworks Multimedia Encyclopedia,1992,CD-ROM). Fatigue is also common.
During the second trimester the mother will most likely experience constipation. Sometimes the uterus will contract may occur. They are called Braxton-Hicks contractions. She may also feel lightheaded and faint. This is caused by the diversion of blood to the uterus, placenta, and fetus. The mother may also experience heartburn because the fetus is growing in size which causes pressure to be placed on the stomach. This stage is more comfortable than the first. The third trimester become more uncomfortable than the first two.
The mother may get hemorrhoids, headaches, swelling of the legs, and varicose veins may occur. The lungs cannot take in enough oxygen so the mother may feel short of breath. Near the end of the fetal developmental stage she may experience pelvic discomfort because the fetus is settling into the position that he will be born by, head down near the pelvis. Insomnia may also be an occurrence days prior to the delivery. The mother may feel false labor There are three signs that can warn the mother that labor is beginning, there are regular contractions, the membrane ruptures ("water breaking"), and mucus mixed with blood. During the last month of pregnancy there are usually contractions that don't mean much. When the contractions are less then about ten minutes apart then that is a sure sign that labor has begun. Sometimes labor will begin with the amniotic fluid flowing out of the vagina.
This means the amniotic sac around the fetus has ruptured and the mother should get to the hospital immediately. "The uterus was contracting, or squeezing, to push you out into the Once the mother is at the hospital she will find it a nice place to be. The hospital equipment has changed over the years and the mother should be quite comfortable. Most of the time the mother will have someone with her, such as a Labor most likely happens in three stages. First the dilatation stage begins. This starts when the contractions begin or the water breaks.
During this stage the cervix, or the opening at the bottom of the uterus, is expanding and opening to a larger size. When the cervix is fully dilated it is about four inches across. While all this is happening the fetus's head is settling into the birthing position. This stage of labor is the longest and can take anywhere from six to twenty hours. If the mother has given birth The second stage of labor is called the expulsion stage. This stage lasts from the time that the cervix is fully dilated until the baby is born. This is the stage where the mother has to push the fetus out of the uterus.
This stage of labor normally takes from just about a few The last stage of the delivery is called the delivery of the placenta. It begins right after the baby is born until the entire placenta is expelled from the uterus. This stage normally takes about fifteen minutes to complete. But it could take up to an hour. This stage is usually the The fetus has a lot of stress being put on him when he is being born. During the contractions the fetus has a small lack of oxygen due too the pressure being put on the placenta and the umbilical cord. During the contractions the fetus's heartrate slows down but regains its strength in between the contractions.
This phase of labor is very punishing on the fetus and the adrenal glands start producing massive amounts of adrenaline and noradrenaline. The adrenaline is important because it helps to keep the heart going if the oxygen supply is cut off. It keeps the blood flowing to the sensitive brain and raises blood-sugar levels. The adrenaline also helps to clear the lungs of the liquid that has been in their since the beginning of the fetus's life. It also helps to prepare the lung for breathing in the outside air. Once out of the mother the babies umbilical cord is cut and the baby is on his own. The mother may experience great pain during this phase of the pregnancy.
To help her relax the husband will usually give her a massage. Just having the father there will make the mother be more comfortable. If she feels the need for pain relievers there are several kinds. She could be given pethidine but that would affect the baby. Another option is inhaling a mixture of nitrous oxide and oxygen. She could also be given a local anesthetic to the nerves of the cervix to relieve the pain. But the most common type of pain relief is the epidural anesthetic.
It numbs the nerves right as the come out of the spinal cord. After the baby is born he is checked by a nurse, measured, and weighed. Then he is wrapped in a blanket and given to the mother. The baby is then moves towards the mother's breast by instinct. This helps to teach the baby how to suck. The baby will feed up to ten times a day. The mother's breasts may become swollen and tender due to the production of milk.
The mother's milk is loaded with nutrients and minerals that is essential to the development of the baby. It is recommended that the child be breast-feed for at least 3 months and if at all possible Bibliography: Cole, J. (1984). How You Were Born. New York: William Morrow and Company, Inc.
