Growth retardation in children mainly includes language, stature, motor, intellectual and psychological aspects, and its recovery training time varies, as well as there are some differences depending on the triggering factors. Children with growth retardation usually have little effect through general training. If the retardation is caused by congenital genetic factors, it is recommended to go to a regular hospital for standardized treatment in a timely manner. The first step is to have a head MRI, EEG, etc. to understand the development of the brain and, if necessary, to administer relevant medication to assist in rehabilitation. If the disease is caused by systemic diseases, the original disease should be actively treated, and the disease can generally be cured to return to normal. If it is caused by malnutrition, the diet should be adjusted in time to ensure adequate nutritional intake, a comprehensive and balanced diet, and good eating habits. In case of developmental delay in children, attention should be paid to observe any other abnormalities or discomfort, and regular visits to the hospital to improve relevant examinations to understand the developmental situation.
