◆ pediatric age installments

In children is in the process of continuous growth and development of all ages have different characteristics of the body, so the entire pediatric period can be divided into several stages, in order to better guide the upbringing and disease prevention. According to the characteristics of growth and development in children, the age of a child, can be divided into six, that the prenatal period, the neonatal period (birth to 28 days), infants (28 days to 1 year old), early childhood (1-3 years of age), young children period (3-7 years), childhood (7 to 12 years of age).

Fetal period

From conception to delivery of a total of about 40 weeks, called the fetal period. Dependent on the maternal fetal period survives, pregnant women, health, nutrition, health, mental state, may affect fetal growth and development, especially in the first three months of conception, fetal organs and organ development and differentiation rapidly , and basically formed the pregnant mother suffered physical, drug, infection, nutrition and other factors, can lead to miscarriage, stillbirth, malformation. Therefore protect pregnant women, guidance pregnancy health, prevention of infection, nutritional intake, pay attention to the health of the fetal period, it is very important.

[Neonatal period]

28 days after birth from childbirth called the neonatal period, the children just left the mother to begin independent survival. Internal organs, not into the whole, the whole is not strong, soft body, the physiological functions were not mature, less able to adapt to the external environment, the need to go through a period of physiological adjustment to gradually adapt to the living environment. Relatively rapid body growth, but the central nervous system is not yet perfect, the cerebral cortex in the inhibitory state, sleep time up to 20 hours a day. The immature neonatal body is very weak, the defense capability of many diseases, and therefore prone to body temperature does not rise, weight loss, illness after cult poison easily spread in the body, leading to serious consequences. The disease is mostly associated with the tire, childbirth and dysplasia, such as birth trauma, asphyxia, umbilical wind, jaundice, stearin swollen psychosis.

【Infancy]

From 28 days after birth to at least 1 year old to infancy, this period children with fresh milk feeding mainly so called suckling period. This period of growth and development, especially rapid, dynamic pediatric developmental rapid physiological characteristics in this period was the most in a year’s time, the body weight increased three-fold compared with the newborn, also an increase of 1.5 times the body length, head circumference, chest circumference The development is very rapid. The rapid growth of the body need a lot of nutrients added, this period is mainly milk food, but must add supplementary food on a monthly basis, in order to meet the needs of growing children. But at the same time the baby spleen often inadequate transport and fatigue, improper feeding, could easily lead to infant diarrhea, Indigestion, abdominal pain, vomiting, stomach disease. Of pediatric lung is also very delicate, not solid guard outside, also prone to colds, cough.

Pneumonia Asthma Syndrome.

From 1 year old to 3 years of age for early childhood. Pediatric weight and length of this period compared with the previous slow, but the physiological function of maturing deciduous teeth gradually at a time, the rapid development of the language, action and thinking activities. After weaning, the varieties of food conversion, the function of the spleen and stomach is weak, likely to cause vomiting and diarrhea, Malnutrition. The increase in outdoor activities, contagious opportunities, such as itching gills, Dayton cough, chickenpox, Dan fever when the line of the increased incidence of the disease, should be good health care.
