Infant seats are specially designed car seats that provide safety and support for babies during travel. They are typically rear-facing and come with a five-point harness system to secure the child. These seats are made to fit infants from birth until they reach a certain weight or height limit, usually around 30 to 35 pounds. Many infant seats are portable, allowing parents to easily transfer their baby from the car to a stroller or inside the home. Some models can be attached to a stroller for added convenience. Proper installation and use of infant seats are crucial for ensuring the safety of the child while traveling.
