Infant car seats are specially designed safety seats for young children, typically from birth to about 12 months or until they reach the weight limit of the seat. They are rear-facing, which provides better support for a baby's head, neck, and spine during a crash. Proper installation is crucial, and many seats come with a base that remains in the car for easy transfer of the seat. These car seats often feature a five-point harness system to secure the child safely. Additionally, they are designed to be lightweight and portable, making it easier for parents to move their baby in and out of the car. Always check for safety ratings and ensure the seat meets current safety standards.
