The only really satisfactory way to minimize the risk of injury or death to children is to provide a restraint system securely fixed to the vehicle. It is essential to limit the child's movement during a crash in a safe and controlled way.
If 0-4 year olds killed in M.V.A.'s had worn restraints, there would have been 93% fewer deaths.
A National Road Safety spokesperson commented that despite all the publicity, only 1% of all toddlers who travel to nursery school are restrained in child car seats.
A restraint minimizes the risk of fatal injury by 71% and serious injury by 61%
The risk of a child being killed when not restrained is
5 times higher
than that of a restrained child

IT IS INTERESTING TO NOTE
A force is exerted on a body equivalent to 30x the body mass when involved in a collision at approximately 50km/hr.
For example, if a baby weighs 10 kg , the force on impact will be 300kg!
