Buick 1993 Skylark Owner's Manual page 46

A
CAUTION:
Never hold a baby in your arms while riding in a
vehicle. A baby doesn't weigh much
--
until a
crash. During a crash a baby will become so
heavy you can't hold it. For example, in a crash
at only 25 mph (40 km/h), a 12-pound (5.5 kg)
baby will suddenly become a 240-pound (110 kg)
force on your arms. The baby would be almost
impossible to hold.
