Infant car seats are specially designed safety seats for young children, typically from birth to about 12 months or until they reach a certain weight limit. They are rear-facing, which provides better protection for a baby's head, neck, and spine in the event of a crash. These seats often come with a base that remains in the car, allowing for easy transfer of the seat in and out of the vehicle. Most infant car seats are equipped with a five-point harness system to secure the baby safely. They are also designed to be lightweight and portable, making it easier for parents to carry their child in and out of the car. Proper installation is crucial for safety, and many seats come with guidelines or indicators to help ensure they are fitted correctly.
