Babies with slow intellectual development should be given comprehensive and integrated rehabilitation treatment, including whole brain development, such as music classes, multimedia attention training and sensory integration training, which can increase the baby’s development of orientation and touch, as well as hand function, acupuncture and physiotherapy, water baths, fumigation and medication. While rehabilitating, it is crucial to find out the causes of mental retardation, such as the presence of high-risk factors before, during or after birth, such as prematurity, cerebral hypoxia, etc., as well as genetic metabolic diseases and chromosomal disorders. Therefore, it is best to bring your baby to the hospital for professional examination.
