Here's why kids should never go down slide on their parent's lap

It may seem like the safer choice, but riding a slide while on a parent's lap actually increases a kid's risk of leg fractures.New research looked at the nature of injuries young children experience on playground slides. Of those under 6 years old, toddlers age 12-23 months had the highest percentage of injuries.

The most common injury overall was a fracture at 36 percent, usually involving the lower leg. In the majority of cases, this type of fractures happens when the child's foot catches the edge or bottom of the slide, then twists and bends backward while sitting on a parent's lap.

"Many parents and caregivers go down a slide with a young child on their lap without giving it a second thought," stated lead researcher Charles Jennissen of the University of Iowa Carver College of Medicine. "And in most cases I have seen, the parents had no idea that doing so could possibly give their child such a significant injury. They often say they would never have done it had they known."

The size and weight of adults apparently plays a big role in the potential for injury. Jennissen said that a young child sliding by themselves is unlikely to get a severe injury to their leg even if the foot catches due to the relatively low forces involved. However, he states that the force generated by the forward momentum of an adult with a child on their lap is much greater, and can easily break a bone if a child's foot gets caught on the slide.

The study's researchers recommended that adults and teens not go down a slide with a young child on their lap. They state that parents and caregivers who elect to do so must use extreme caution to prevent the child's foot from catching on the slide's surfaces.

The study's findings will be presented Monday at the American Academy of Pediatrics National Conference in Chicago.
