Because babies' brains are heavy and their necks are not fully developed, they are more susceptible to injuries - and could even die - from being shaken.

Because shaking causes the brain to swell, a shaken baby can develop irreversible brain damage, spinal cord injuries, blindness, cerebral palsy, loss of hearing, seizures, learning disabilities and even death.

Caregivers may get upset by a child's crying and shake a baby or child out of frustration. After enough shaking, a baby will stop, either because the child is unconscious or because the brain has swelled and the baby is unable to cry.
