The first period is called the germinal period. This time frame consists of the first fourteen days of the baby’s development starting with conception. During these two weeks, the fertilized egg makes it’s way into the uterus for implantation in the lining of the uterus. The next period, the embryonic period starts here. The embryonic period lasts the third through the eighth week of pregnancy.
This process will occur in states and can be monitored throughout each week of pregnancy. Through a process called differentiation, the embryo rapidly grows and takes on its main external features. Though some doctors and mothers count the pregnancy by weeks, for this paper it will be grouped into months. Pregnancy consists of a nine month incubation period inside the womb. Each month has their ... ... middle of paper ... ...ywhere from ten minutes to forty-eight hours.
Then once they learn all of that, they have to learn to get along with their body again, because adolescence starts. They have to mature into a good adult. While still in the womb, a baby develops all the time. The first trimester is a busy time in the life of a child. During the first month the baby gains dark spots for the eyes and is as long a grain of rice.
The internal cells become the embryo, the human organism at this time. The external cells become the placenta, which provides nutrients and oxygen for the baby. Formation of organs takes place during the embryonic stage, and they also begin to operate. Lastly, the embryonic stage begins around two weeks after conception through roughly eight weeks. After the embryonic stage, the fetal stage begins and lasts until the birth of the baby.
The beginning of the third week after conception marks the start of the embryonic period, a time when the mass of cells becomes a distinct human being. The embryo begins to divide into three layers each of which will become an important body system (Cherry, 2015). Approximately 22 days after conception, the neural tube forms. Cherry (2015) argues that this tube will later develop into the central nervous system including the spinal cord and brain. Around the fourth week, the head starts to form quickly followed by the eyes, nose, ears, and mouth.
Coming up to seven and eight weeks, the organs of the embryo have started to function and the embryo is now called a fetus (Miller & Levine). The time after the ninth week to the birth of the child is referred to as the fetal period. During the fourth, fifth, and sixth month the features of the body start to form and become more complex and specialized which gives ... ... middle of paper ... ...reater respect for the amazing process of development.

The actual definition of child development is the biological, physical, and emotional changes that occur from birth until the end of adolescence. There are many different stages of development, it starts in the womb. It takes at least 20 weeks for a child to fully develop inside the womb starting the day of conception. A full pregnancy lasts 42 weeks. During the first week
Caring for premature babies may add some stress, which means that mothers should look for support and at the same time, take care of themselves, too. How Is Your Baby Developing at 1 Month? 1． Physical Development Head shape changes A baby who is delivered through the vagina usually has an elongated head at birth due to moulding of the soft skull to accommodate itself through the pelvic opening. However, by one month (four weeks), the head becomes more symmetrical and rounder in shape. Starts to lift her head a little At one month, a baby who is lying on her tummy may be able to lift her head a little.
194). As infants grow they develop something called a working model which is a reference point for experiences later in life. Depending on our parents emotional availability we can develop either a working model based in love, support, and confidence or a working model based in insecurity, self-doubt, and unpredictability. Much of this frame work lays the foundation for the rest of our lives. The first two years of a infants development is crucial.
Through these senses they explore their world and sensations occur. Perception occurs when the brain processes these sensations. Infant movements are involuntary (reflexes). Reflexes help the infant survive until they gain control of their body and can make movement for themselves. Infants experience the majority of their growth during the first year.
