Summarize the following:
Car seats are tested for their performance in crashes, and various safety organizations publish the results. These organizations and safety ratings vary by country; Australia, for example, has some of the strictest safety ratings for car seats. In Canada, Transport Canada publishes information about car seats. In the United States, consult Consumer Reports or the Insurance Institute for Highway Safety for information about safety ratings. Additional information can also be found at the National Child Passenger Safety Board’s website. If a particular car seat has defects in it, its manufacturer may have issued a recall. The car seat would then be returned to the manufacturer for a new seat or a refund. When you are looking into different car seats and brands, check to see if there have been any recalls on the particular car seat model or the brand itself. Search online for “car seat recall” to find the most up-to-date information. All car seats have basic features that will ensure a solid level of safety and comfort for your infant. Many car seats do, however, have additional features. These might include additional side-impact cushioning, extra padding all around the seat, or an anti-rebound bar at the foot of the car seat. At the end of a major crash, during the rebound, the car seat might bounce up and hit the seat in front of it. The anti-rebound bar, available in newer seats, is intended to minimize the impact that the car seat will take. There should be one strap per limb: one for each upper arm and one for each thigh, as well as one for the area between the child's legs. There are alternative restraint systems, such as plastic shields and T-bar restraints, but the strap system is more customizable, which can make the seat more comfortable for your child’s size. Starting in 2002, all infant car seats were required to be compatible with the LATCH system, which stands for Lower Anchors and Tethers for Children. The LATCH system allows infant car seats to attach directly into a car seat rather than being held in place by the seatbelt. Hooking up directly into a car seat will maximize the safety of your child in your vehicle. The LATCH system is compatible with or known by different names in other countries. In Canada, the system is called the Universal Attachment System (UAS). In Europe, the system is called ISOFIX, and ISOFIX compatible in Australia. As car seats are used, their materials deteriorate and can become less reliable. Car seat manufacturers imprint their seats with expiration dates, typically 6 years after the date of manufacture. This date can usually be found imprinted into the plastic on the back or bottom of a car seat. Ensure that the car seat has not been in a crash; this might compromise the integrity of the seat and its materials. If the seat is older than 6 years, it is not recommended for use.

Summary:
Research safety ratings for a range of car seats. Pay attention to recalls. Consider the car seat’s safety features. Make sure the infant car seat has a 5-point safety harness. Choose an infant car seat with LATCH tethers. Only buy or borrow used seats from trusted family or friends.
