What behaviors can prove the baby's current development is very healthy? What is the basis?

A child within four weeks (28 days) after delivery of a pregnant woman is called a newborn. Every human organ and phylogenetic tree of newborn is not perfect, and the whole body immune function is poor, so it is very easy to get sick and get new. Neonatal period is also a stage with high mortality. Careful nursing is the key step to prevent neonatal diseases and ensure their physical and mental health. So pay attention to careful nursing. Through the doctor's analysis, it is believed that the physical and mental health of newborns should have ten levels of norms: newborns cry several times after birth, and then gradually inhale through the lungs. Inhale 40-50 times per minute for the first two weeks. The neonatal pulse rate is 120- 140 beats per minute.

The normal weight of newborns is 3000-4000 grams, and less than 2500 grams is immature. The first two days of the newborn's stool was dark green, sticky, flute-shaped, colorless and tasteless. After breastfeeding, it gradually turns pale yellow (orange yellow or pale yellow). A normal full-term baby is born at 37 to 42 weeks of pregnancy. A successful baby with a birth weight of 2,500 to 4,000 grams and no abnormalities or symptoms. Normal full-term features: respiratory tract. The growth and development of respiratory center is immature, the inspiratory law is often irregular, and the working frequency is fast, 40 times per minute. The key lies in diaphragm movement, mainly abdominal breathing. Cycle. Newborn's heartbeat fluctuates greatly, with 100 ~ 150 beats per minute, with an average of 120 ~ 140 beats per minute and an average blood pressure of 70/50mmhg.

The swallowing function of full-term infants in digestive tract has improved, but the sphincter below esophagus is relaxed and the stomach is horizontal. The pyloric dilatation of the stomach is relatively developed, which is easy to produce galactorrhea and nausea and vomiting. After delivery 10 ~ 12 hours, the stool will be discharged gradually, about 2 ~ 3 days. Fetal feces is dark green, which is composed of increased secretions in the baby's stomach, bile, and swallowed amniotic fluid of pregnant women. Urogenital system. Newborns usually urinate within 24 hours after birth. If you don't urinate within 48 hours after birth, be sure to check the reason. The newborn baby urinates very little on the first day, about 10~30mL. It is normal to urinate within 36 hours after birth. With the intake of water during breast-feeding, children's urine output gradually increases, reaching more than 10 times a day, with the total output reaching 100~300mL a day and 250~450mL around the full moon. It is normal for children to urinate frequently.

Human body temperature: The normal body temperature of newborns is between 36℃ and 37℃, but the nerve center function of human body temperature of newborns is not perfect, and the body temperature changes greatly due to the harm of external environment temperature and natural environment. Newborns have thin body fat and large body surface area, which is very easy to expel heat. Therefore, newborns should keep warm, especially in winter, and the room temperature should be kept at 18~22℃. If the indoor temperature is too low, it is very easy to cause scleredema. Newborns can excrete meconium shortly after birth, which is dark green and becomes transitional defecation within 3 ~ 4 days. If meconium is found within 24 hours after birth, it is recommended to check it to eliminate congenital malformation, such as anal atresia or Hirschsprung's disease. Physiological weight loss: the water content in the newborn accounts for 65% ~ 75% of the body weight. In the first few days after birth, due to drinking less milk and excreting more water, the body weight can be reduced by 4% ~ 7% compared with that at birth, but it should not exceed 10% of the birth weight.
