Rear-facing
Rear-facing car seats hold infants and toddlers, securing their necks and spines from injuries in a crash. They are also safer since they distribute the impact force over an area larger than the surface which reduces spinal cord injuries.
Parents are often tempted to change their children to forward-facing car seats before they're ready, but the American Academy of Pediatrics recommends keeping them rear-facing for as long as is possible. The manufacturer will tell you when your child is ready to go forward-facing.
The heads of children are huge relative to their bodies and still growing, which makes them more vulnerable to crash. In reality children's heads could generate up to 25 times the force of their body weight in the event of a collision. This is more than enough to cause a fatal injury. This is the reason why children who sit in a car seat with their backs forward are at the greatest risk of fatal head injuries.
Many parents believe that their children have larger necks and are able to make the transition to a car seat that faces forward faster. However, it's important to keep in mind that a child who is in the 95th percentile isn't any stronger than the 5th percentile child, and no amount of teen push-ups can alter this.

Whiplash is still a possibility even if the neck muscles of the child are strong. This is especially applicable to children who are younger, such as infants.
A forward-facing child is also more likely to strike their head on the dashboard or in front of the window during an accident. Depending on the nature of the crash and speed at which the car is moving the head could be forced into the seat and may break the skull or spinal cord.
The current safety standards mandate that kids remain rear-facing until they attain 20 pounds and one year old age. This is because children younger than one year don't have the strength of their necks to withstand the forces involved in a head-on collision, which tends to be the most serious type of accident in which cars are involved.
Utilizing a harness and tether while rear-facing helps to keep the kid's head stable and reduces the strain on their necks. In addition, a rear-facing child is less prone to head injuries since the impact is cushioned with the body of the seat.

The lap part of the belt should be placed across the thighs and not the stomach. Booster seats come with a built-in belt guide to ensure that the belt is positioned correctly.
Booster seats can be purchased with or without a backrest. The most commonly used booster seat is the high-back type that offers neck and head support for children. This is a good option for vehicles that have low backs and have no headrests. Backless boosters are cheaper, but they don't provide neck or head support. Certain all-in-one boosters allow you to switch between harness and boost modes. They are suitable for children from to 65 pounds in harness mode, and up to 100 pounds when used as boosters.
Some boosters have an anchor system for lower anchors (LATCH) that hooks to the lower anchors of the vehicle and a tether in the event that it is available. Others require the vehicle seat belt to secure them in place. Go through the manual of your car to see if you can use the lower anchors inside your vehicle, and then read the instructions for booster seats to learn how to use them.
