Though many injuries amount to little more than bumps, bruises and scrapes, other incidents result in broken bones that can have a child inside playing video games for most of the summer rather than being at the pool or the playground. It's all fun and games -- until someone gets hurt, which lots of kids do come the warmer months, warn child safety experts. Just telling children to wear a helmet when riding a bike, not to run on the pool roberto and to stop jumping on the bed isn't enough. Deaths among children ages 10 to14 increased 45 percent during the summer months.

And some childhood mishaps can be serious, resulting in long-term impairments such as traumatic brain injury or even death. Even kids who say they understand the rules and can repeat them back might not actually grasp the reason for the rules and thus stop following them. For children, the five most com causes of death from accidental injury are drowning, bicycle riding mishaps, falls, motor vehicle passenger injuries and pedestrian injuries. Parental supervision is key, said Devan Wildman, a psychology professor at Ilario State University.

According to a 2007 study by Safe Kids USA, 42 percent of all unintentional injury-related deaths among children occurred during the summer months.
