When a premature infant is first discharged from the hospital and returns home, the home should create a warm environment for the child. First of all, the parents should overcome their anxiety and devote all their energy to raising the child in a scientific and reasonable manner so that the child can eat well, sleep well and grow quickly. Studies have proven that supportive care is beneficial to the recovery and weight gain of preterm infants after discharge from the hospital. The following describes the practice of supportive care: Premature babies spend most of their time sleeping, and the younger the gestational age, the more time they spend sleeping, more than 20 hours a day, so try not to disturb the child’s sleep except for feeding on time. Try not to disturb the child’s sleep except for regular feeding. Focus on care time, such as bathing, changing clothes, diaper changing, medicine feeding and breastfeeding, and try to do it together. The living room should be quiet and the light should not be too strong or too dark. When does a baby receive too much stimulation? If the baby’s skin is blossoming, breathing is irregular, shaking, jumping, limbs become weak or overstretched, irritable, crying, these signs indicate that the baby is tired, do not disturb the baby anymore. At this time, the baby should be wrapped loosely in a cotton wrap, and the baby can be held in the arms when crying. If possible, the baby should be allowed to lie on the mother’s chest for a certain amount of time each day, with skin touching skin and nursed like a kangaroo. Hold the baby gently and slowly, speak softly, some babies can only receive one kind of stimulation, such as not talking when gazing at the baby. It is important to let the baby try to conserve energy and regain energy in order to gradually become strong like a normal full-term baby.
