Babies with cerebral palsy can raise their heads, but they take longer to raise their heads relatively steadily and usually cannot maintain a stable erect head at 3-4 months of age. This is because there are residual primitive reflexes and abnormal postures leading to instability of the baby’s shoulder joints, resulting in unstable head erections and inability to roll over. Most babies have abnormalities in the perinatal period, such as prematurity, hypoxic-ischemic encephalopathy, kernicterus, etc., and are accompanied by increased muscle tone in the limbs, head tilting, body jerking, or body weakness. If abnormalities are present after evaluation, comprehensive rehabilitation is needed.
