Final answer:
Children should remain in a rear-facing safety seat until they are at least 2 years old or have reached the maximum height and weight limit allowed by the car seat manufacturer. Rear-facing seats provide the best protection for a child's head, neck, and spine. Once a child outgrows the rear-facing seat, they can transition to a forward-facing seat with a harness.
Step-by-step explanation:
In regards to child safety seats, children should remain in a rear-facing seat until they are at least 2 years old or have reached the maximum height and weight limit allowed by the car seat manufacturer. Research has shown that rear-facing seats provide the best protection for a child's head, neck, and spine in the event of a crash. This is especially important for infants and young children, as their bodies are still developing and their bones and ligaments are not as strong as those of adults. Once a child outgrows the rear-facing seat, they can transition to a forward-facing seat with a harness. It is important to always follow the manufacturer's guidelines and local laws regarding child safety seats.
