Child Safety Seat Information
The tether is located on the top rear of convertible, combination, and all-in-one car seats. It’s adjustable and has a hook and strap that connects to one of your vehicle’s tether anchors. Most rear-facing car seats in the United States do not use a tether for installation. However, installations vary from model to model, so you must review your particular car seat’s instructions and your vehicle’s owner manual carefully.
For young infants, the seat used is an infant carrier with typical weight recommendations of 5-20 lb. Most infant seats made in the US can now be used up to at least 22 pounds (10.0 kg) and 29 inches (74 cm), with some going up to 35 pounds (16 kg). In the past, most infant seats in the US went to 20 pounds (9.1 kg) and 26 inches (66 cm). Infant carriers are often also called "Bucket Seats" as they resemble a bucket with a handle. Some (but not all) seats can be used with the base secured, or with the carrier strapped in alone. Some seats do not have bases. Infant carriers are mounted rear-facing and are designed to "cocoon" against the back of the vehicle seat in the event of a collision, with the impact being absorbed in the outer shell of the restraint. Rear-facing seats are deemed the safest, and in the US children must remain in this position until they are at least 1 year of age and at least 20 pounds (9.1 kg). although it is recommended to keep them rear-facing until at least 2 years old or until they outgrow the rear-facing car seat height and weight, whichever is longer.
The American Academy of Pediatrics says to “make sure the seat is at the correct angle so your infant’s head does not flop forward. Many seats have angle indicators or adjusters that can help prevent this. If your seat does not have an angle adjuster, tilt the car safety seat back by putting a rolled towel or other firm padding (such as a pool noodle) under the base near the point where the back and bottom of the vehicle seat meet.” Safety seats come with an instruction booklet with additional information on the appropriate angle for the seat.

Heatstroke is one of the leading causes of non-crash-related fatalities among children. Vehicle heatstroke occurs when a child is left in a hot vehicle, allowing for the child’s temperature to rise in a quick and deadly manner. Heatstroke begins when the core body temperature reaches about 104 degrees and the thermoregulatory system is overwhelmed. A core body temperature of about 107 degrees is lethal. Unfortunately, even great parents can forget a child in the back seat. Other risk factors include caregivers who aren’t used to driving kids, or whose routine suddenly changes.
A study of car crash data from 16 U.S. states found that children under the age of 3 were 43% less likely to be injured in a car crash if their car seat was fastened in the center of the back seat rather than on one side. Results were based on data from 4,790 car crashes involving children aged 3 and younger between 1998 and 2006. According to data, the center position was the safest but least used position. However, economist Steven Levitt (see below) has demonstrated that car seats do not reduce fatalities when compared to regular seat belts.
