Child safety seat counseling: three keys to safety.

The number one cause of death for children younger than 14 years is vehicular injury. Child safety seats and automobile safety belts protect children in a crash if they are used correctly, but if a child does not fit in the restraint correctly, it can lead to injury. A child safety seat should be used until the child correctly fits into an adult seat belt. It is important for physicians caring for children to know what child safety seats are available and which types of seats are safest. Three memory keys will help guide appropriate child safety seat choice: (1) Backwards is Best; (2) 20-40-80; and (3) Boost Until Big Enough. "Backwards is Best" cues the physician that infants are safest in a head-on crash when they are facing backward. "20-40-80" reminds the physician that children may need to transition to a different seat when they reach 20, 40, or 80 lb. "Boost Until Big Enough" emphasizes that children need to use booster seats until they are big enough to fit properly into an adult safety belt.
