A neonate is a child who is delivered from the mother, from the time the umbilical cord is tied until 28 days after birth. Newborns need to adapt to the new environment as they move from the intrauterine environment to the extrauterine environment, and their immune function is very poor at this stage, so if a mild infection occurs, more serious complications can occur, even sepsis. Therefore, it is necessary to try to avoid the cold and avoid respiratory infections. The growth rate of the newborn baby is very fast, weight can increase 1-1.5kg, height can increase about 5cm. Breastfeeding should be done as much as possible during this period, because the nutrients in breast milk are very balanced and colostrum is rich in immunoglobulins, which can enhance the immunity of newborns. In short, the care of newborns is extremely important. Wash the buttocks with warm water after each stool and change diapers regularly to prevent red buttocks and diaper rash. Clothes should be wide and soft, and hands should be washed strictly before and after contact with the newborn to prevent cross-infection.
