Safety 1st is the number one reason why we have car seats now. Have seat belts now. Have the helmets for bikes. Have elbow and knee pads. Have laundry detergent and other products up high. Reasons for safety concerns. Reasons for high chain locks when you have small children. Reasons for Co detectors. Reason for childrens harness when you take them for walk's and stroller seat belts. All of these reasons why they make sense.
