Symptoms of cerebral palsy in a 50-day-old child can be manifested in many ways, such as easy to frighten, crying, clenching fists, rigidity, etc. Depending on the degree of the disease and their own conditions, the symptoms of the child vary, including motor and intellectual disorders. 1. Easily startled: Most children are easily startled, cry incessantly, have difficulty falling asleep, and eat poorly. 2. Fist clenching: Usually, babies can keep their fists in a clenched position for about three months after birth, but children with cerebral palsy may still keep their fists in a clenched position for up to five months. 3. Stiffness: Children with cerebral palsy have stiffness in their limbs, which is often noticeable when they are dressing. 4. Premature development: Children with cerebral palsy may roll over prematurely, but in a reflexive rather than a segmental manner, like a tumbler. Symptoms of cerebral palsy may vary. If your child is suspected of having cerebral palsy, it is important to see a doctor as soon as possible to receive professional diagnosis and treatment.
