Babies with mild cerebral palsy usually smile, chase objects and eat their hands, but babies with severe cerebral palsy may not chase objects or eat their hands. The term “cerebral palsy” refers to a syndrome of postural and motor dysfunction caused by non-progressive brain damage during the immature stage of brain development within one month after birth. 1. It is not possible to judge cerebral palsy completely on this basis. Because laughing, chasing and eating hands are normal physiological movements, babies with cerebral palsy usually suck their fingers when they are insecure, and they can’t help but laugh when they are happy. Because of their high muscle tone, babies with severe cerebral palsy are usually unable to eat hands and chase objects. Cerebral palsy is usually related to the development of the baby in the womb and the condition of the baby at birth. If your baby has cerebral palsy, parents should be patient and teach your baby to learn, and communicate with your doctor to develop a rehabilitation plan and follow it.
