Some little babies are discharged home with oxygen. It is important to gradually reduce the use of oxygen, using some when feeding and none when calm. After a week, you should go back to the hospital to check if you can stop oxygen. If the baby does not eat milk well, spits up easily and does not gain weight after coming home, you should also go back to the hospital for a review in time. Generally speaking, within 6 months after discharge from the hospital, premature babies should be rechecked once a month; after 6 months, depending on the baby’s condition, the doctor will decide to recheck once every 1-2 months. After one year of age, the baby will be reviewed once every 2-3 months until 2 years of age. At each review, the doctor will ask about the baby’s feeding and care process and what progress and changes have occurred each month. The doctor will check the baby’s physical growth and neuromotor development and inform the parents where the baby is at the same age, what is good and what are the gaps. Through regular follow-up visits, doctors are able to detect early signs of abnormalities in the development of premature babies, such as abnormal muscle tone or abnormal posture, and provide targeted guidance on training methods for early intervention based on the baby’s specific performance. This will minimize the occurrence of neurological sequelae and enable the baby to grow up healthily.
