Head Injury, Age 3 and Younger - Topic Overview

Almost all children will bump their heads, especially when they are babies or toddlers and are just learning to roll over, crawl, or walk. These accidents may upset you, but your anxiety is usually worse than the injury. Most head injuries in children are minor.

Head injury occurs more often in young children than adults. When compared with adults:

  • Young children can't control the movement of their heads as well as adults.
    • Their heads are larger in relation to their bodies.
    • Their neck muscles are not as well developed.
  • Young children's legs are somewhat shorter in proportion to the rest of their bodies. This makes a child's center of gravity closer to the head than an adult's center of gravity.
  • Young children are more likely to have an accident or fall as they learn new skills such as walking, running, and jumping.

Bumps, cuts, and scrapes on the head and face usually heal well and can be treated the same as injuries to other parts of the body. A superficial cut on the head often bleeds heavily because the face and scalp have many blood vessels close to the surface of the skin. This bleeding is alarming, but often the injury is not severe and you can stop the bleeding with home treatment. When bleeding does not stop with home treatment, visit a doctor because a young child can lose a large amount of blood from a deep cut on the head.

The most common serious head injuries in young children are caused by falls and abuse (inflicted head injuries), such as shaken baby syndrome. Serious head injuries may involve injuries to the brain. The more force that is involved in a head injury, the more likely it is that a serious injury to the brain has occurred. If there has been a high-energy injury to the head, there is a greater likelihood that a serious injury has occurred. When a high-energy injury occurs, it is even more important to assess the child for signs of a serious head injury.

Following an injury, it can be hard to tell the difference between a mild traumatic brain injury (concussion) and a more serious brain injury. Watch the child carefully for 24 hours after a head injury to see whether he or she develops any signs of a serious head injury.
