THE BEGINNING
Prenatal development is the period in development from conception to the onset oflabor. Perinatal period is the period beginning about the seventh month of pregnancyand continuing until about four weeks after birth. Postnatal development is the periodin development the follows directly after birth. The germinal stage is the stage lastingabout ten -fourteen days following conception before the fertilized egg becomesimplanted in the uterine wall. The embryonic stage is the stage in which majorbiological organs and systems form. The fetal stage is the stage in which is marked byrapid growth and preparation of body systems for functioning in the postnatalenvironment. Viability is the ability of the baby to survive outside the mother’s womb.The gestational age is the age of the fetus derived from onset of mother’s lastmenstrual period. The number of older mothers is on the rise in the U.S. as womenpostpone pregnancy to establish careers or for other reasons. Healthy women older
The placenta is a supportorgan formed by the cells from both blastocyst and uterine lining; serves as exchangesite for oxygen, nutrients and waste products. Most infant’s are born in a hospital, although there are some alternative birth settingssuch as, birthing centers (home-like setting). A large part of their time in engaged in REM sleep, astate that may provide them with stimulation even when asleep. Despite the immediate obstacles facinglow-birth weight babies, many become normal children and adults. Then, transition, the baby shifts to thebirth canal. During the delivery, a fetal monitoring device isused to monitor fetal heartbeat. These are just a few of the many diseases that can causeharm: toxoplasmosis, hepatitis B, diabetes, and chlamydia. Another reason is the complicated nutritional needs of teenagers. Statistics show that births directlysupervised under a midwife, have less complications and distress. Diets, while pregnant, mustbe sufficient not only in number of calories but also with respect to the right amount ofproteins, vitamins, and other nutrients. Not in all cases does the womanhave to be certain age. After the resting in the birth canal, the baby is ready to be born. Support within the womb: the placenta. Lack of prenatal care is a big reason.
