Children Everyone in a vehicle needs protection! That includes infants and all children smallerthan adult size. In fact, the law in every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle. Smaller Children and Babies Smaller children and babies should always be or restrained in a child infant restraint. The is instructions for the restraint will say whether it the right type and for yourchild. A very size young child's hip bones are so small thata regular belt might not stay on the hips, as it low should. Instead, the belt likely be over the will child's abdomen. Ina crash, the belt would apply force right on the child's abdomen, which could cause seriousor fatalinjuries. So, be sure that any child small enough for onealways properly is restrained in a child or infant restraint. 1-48
