What is the correct advice regarding car seat safety for a newborn?

The correct advice regarding car seat safety for a newborn emphasizes that the baby should remain in a rear-facing position until at least the age of 2. This recommendation aligns with guidance from pediatric organizations that highlight the importance of rear-facing car seats in providing the best protection for a developing child's head, neck, and spine in the event of a collision.

Rear-facing car seats are designed to absorb the impact of a crash, distributing the forces more evenly across the child's body and minimizing the risk of injury. Keeping a child rear-facing until they reach the maximum height or weight limit set by the car seat manufacturer further enhances safety. Therefore, this option is crucial as it directly relates to the developmental needs of infants and toddlers and maximizes their safety while traveling in a vehicle.

In contexts where other options may suggest positioning or adjustments that do not conform to best practices, such as placing harness clips inappropriately or suggesting an incorrect angle for the car seat, this answer stands out by adhering to established safety protocols.
