Cerebral palsy in six-month-old babies mainly manifests as developmental backwardness, abnormal muscle tone and abnormal posture. 1. Developmental backwardness: Both gross and fine motor movements are slower than those of children of the same age. If the disorder is mild, the hands and feet may appear to be slightly inflexible or clumsy, but if it is serious, the hands may not be able to grasp things and the feet may not be able to walk. 2. Abnormal muscle tone: Abnormal muscle tone is one of the characteristics of children with cerebral palsy. Babies with cerebral palsy have very poor body coordination, stiffness and rigidity, and the muscle tissue is hyperactive. Most of the babies will have elevated muscle tone and very few will have low muscle tone. 3. Postural abnormalities: Children with cerebral palsy may show generalized weakness, weakness or tightness of limbs, jerking and startling. Children with cerebral palsy may also have the buttocks higher than the head, difficulty in lifting the head, scissor-leggedness, and drop of the toes. The symptoms of cerebral palsy in six-month-old babies may include other symptoms. Parents should pay attention to the abnormal behaviors of their children and bring them to the hospital in time, so that they can be diagnosed by the doctor and treated in time.
