Shaken Baby Syndrome

Shaken Baby Syndrome is a term used to describe signs and symptoms resulting from the violent shaking of an infant or small child.

With or without impact trauma, shaking a baby is child abuse. It is a form of assault, which is a criminal offence as set out by the Criminal Code of Canada. The police will investigate incidents of Shaken Baby Syndrome.

Why would anyone shake a baby?

It is difficult to understand why anyone would shake a baby. Babies may be shaken as a result of crying or other triggers for frustrated caregivers.



Which children are most at risk?

Shaken Baby Syndrome can happen at any age. It is most common in children under one year of age as they have weak neck muscles and heavy heads. Even a few seconds of shaking can cause serious damage to a young child.



Can an infant get Shaken Baby Syndrome through rough play?

No, the force necessary to produce injury is such that it cannot occur in normal day-to-day activities, a fall or even a resuscitation attempt.



What are the signs of Shaken Baby Syndrome?

A child that has been shaken may experience:
  • irritability
  • lethargy
  • vomiting
  • seizures
  • unconsciousness


What injuries will a shaken baby have?

A child who has been shaken may suffer brain damage, developmental delays, blindness, seizures or even death.



What can you do to prevent Shaken Baby Syndrome?

  • Never shake a baby.
  • Know your own breaking point and have a plan for what to do if it happens.
  • Inform your child's caregivers about the dangers of shaking a child.
  • Educate your own children of the dangers of shaking a baby.
