Typical symptoms of a child with cerebral palsy at 3 months of age may include motor deficits, perceptual deficits, and feeding difficulties. Various abnormalities that occur during the mother’s pregnancy and after the child is born may cause cerebral palsy. Most parents will discover the abnormalities as the child grows, and early detection and treatment will improve recovery. 1. Motor impairment: at three months of age, the child’s head will still be tilted back if pulled up in the supine position; he cannot lift his head in the prone position; when others assist in maintaining the sitting position, the vertical head time is less than 10 seconds, and the lower limbs are rigidly extended. 2. Perceptual impairment: less or more crying, easily frightened; children with spastic cerebral palsy Children with spastic cerebral palsy usually have a mute, nearly expressionless expression. Children with spastic cerebral palsy usually have a blank expression and are nearly expressionless. Children with tardive cerebral palsy often have sad faces, and children with delayed cerebral palsy are unable to respond to others’ calls. 3. In order to achieve the best treatment effect for cerebral palsy, it is necessary to achieve the “three early stages”, i.e. early detection, early diagnosis and early treatment. In fact, in the early stage of infant, especially within 3 months after birth, the brain tissue is still in a rapid developmental stage and has great plasticity, which is the best time for treatment. Therefore, if an abnormality is found in a premature child, it is important to go to the pediatric department for relevant examination within 3-6 months, so that early measures can be taken to treat the problem.
