All people who have cerebral palsy (CP) have some problems with body movement and posture. But many babies don’t show signs of CP at birth. Parents and caregivers may notice the first signs of CP. For example, the baby may not roll over, sit, crawl, or walk at the expected ages.
Signs of CP may become more obvious as the child grows. Some developmental problems may not appear until after a baby’s first year. The brain injury that causes CP doesn’t get worse over time. But its effects can appear, change, or become more severe as the child gets older.
