Heredity: Organisms reproduce races through various ways of reproduction, which ensures the continuity of life between generations. This is called heredity.
Eugenics: Eugenics is "genetic health". Generally speaking, eugenics is to let excellent children be born, or to let excellent people survive and grow up healthily.
Eugenics is closely related to heredity. The main goal of eugenics is to prevent the birth of congenital malformation and hereditary diseases as much as possible, so as to reduce the incidence of hereditary diseases.
2. How to achieve prenatal and postnatal care?
Eugenics should include excellent love, marriage, pregnancy, childbirth, education and education.
Excellent love: it is to find excellent people to fall in love with, that is, to choose excellent people in morality, intelligence, physique and beauty as love objects. Among them, good health and normal intelligence are very important.
Excellent marriage: refers to marrying excellent, like-minded and strong people.
Excellent pregnancy: choose the best period of pregnancy, do a good job of health care during pregnancy, avoid contact with poisons, create all favorable conditions, and promote the normal development and growth of embryos and fetuses.
Excellent delivery: refers to the normal delivery of the fetus without any damage or influence.
Parenting: refers to the correct feeding methods and reasonable nutrition to promote the normal growth and development of children.
Excellent education: it means that children receive good education and careful training.
The importance of prenatal and postnatal care;
Healthy children not only bring happiness to happy families, but also contribute to the prosperity of the country and the nation. Eugenics is a science that specializes in studying human heredity and improving human race.
The purpose of eugenics is to improve the quality of the population, including two aspects: first, active eugenics; The second is negative eugenics.
Active eugenics is an individual eugenics that promotes physical and intellectual Excellence. That is, through the research of molecular biology and cell molecular biology, we can modify and transform genetic material, control individual development, make future generations more perfect, and truly achieve the purpose of manipulating and transforming human beings themselves.
Negative eugenics is to prevent or reduce the birth of individuals with serious hereditary and congenital diseases, that is to say, to reduce the birth of unhealthy individuals. The latter is the most basic and practical preventive eugenics of human beings. It is impossible to improve the quality of the population without reducing the birth of idiots and deformed children.
The birth of a child with congenital dementia will bring great pain to parents and become a burden to family and society. His existence means nothing to society. Therefore, it is an important prerequisite for family happiness to prevent and find fetal abnormalities as soon as possible and block the continuation of genetic diseases and birth defects.
At present, China advocates that a couple should have only one child. Giving birth to a healthy and intelligent child is the common aspiration of family and society. To realize this wish, we must have certain scientific knowledge of eugenics and excellent education. The knowledge of prenatal and postnatal care is the premise of getting healthy children, and excellent education and teaching are the guarantee for the healthy growth of children. If your child is born in good conditions, but after birth, unscientific parenting methods will also affect the child's intellectual and healthy growth. For example, children born in summer have prickly heat or diaper rash is very serious, so the children are in a bad mood; Coupled with poor nursing, the child's nasal cavity was not cleaned in time, the ventilation was not smooth, and the child could not eat well; If you don't cut your nails, the child will scratch his face. As long as there is something wrong with the child, he or she will be agitated and affect sleep.
Feed your child every time every day, keep the diapers dry and the buttocks clean and hygienic, often bathe your child, keep your body clean, do baby gymnastics, sunbathe and do outdoor activities to ensure that your child gets enough sleep. In short, it is very important to give children a motherly upbringing, so it is very important to arrange their daily life and rest. Including the close combination of excellent education and excellent education from the first day of birth. Because the baby left the mother's body after birth, everything is his learning process. As you get older, everything your baby can touch needs to be gradually adapted. This adaptation process is also a process of education, rather than waiting for the baby to develop naturally. Breastfeeding a baby is a good opportunity to promote growth and development.
For example, breastfeeding is the most suitable feeding method for infants. No matter from the nutritional quality contained in breast milk or the proportion of various nutrients, breast milk is superior to milk. Because breast milk contains immune bodies against infectious diseases, infants can enhance their disease resistance by getting it from breast milk. In particular, breast milk contains secretory immunoglobulin, which can not only prevent respiratory diseases in children, but also resist digestive diseases. Therefore, as a mother, as long as she has milk, she must do her duty of breastfeeding for at least 3 ~ 4 months. Why should we emphasize breastfeeding? The more important issue is to let the baby get "early education" (that is, early education for O ~ 3 years old). Established a good parent-child relationship. Whenever breastfeeding, the mother should hold the baby in her arms in a comfortable mood, let the baby hold most of the nipples and areola, and while listening to music, smile and nurse the baby kindly, so that the child will feel very comfortable and look at her mother with a smile. Through breastfeeding, mother and child are soul mates, which is the best way to cultivate feelings. In such an environment, the baby's bright eyes sparkle with his mother's every move, word and deed, so parents are the children's first teachers (especially mothers). From the baby's smile, people can feel the vitality and happiness of life. A child's good mood is one of the signs of health. Everything from o to 3 years old should be combined with the daily schedule, through which good hygiene habits, civilized behavior, excellent moral character and high sympathy can be cultivated from an early age. Children's intelligence needs adults to guide development rather than wait, so parenting is related to people's life and is of great significance.
