An infant car seat is a safety device designed to protect babies during car travel. It is specifically made for infants weighing up to 30-35 pounds and typically features a rear-facing design. This orientation helps to support the baby's head, neck, and spine in the event of a collision. These car seats are usually equipped with a five-point harness system to secure the baby safely. Many models are portable, allowing parents to easily transfer the baby from the car to a stroller or home. Proper installation and use are crucial for ensuring the safety of the child while traveling.
