An infant car seat can only be used rear-facing and is used for a limited amount of time, usually for the first 1 to 2 years. It offers the convenience of a 2-part design which consists of the car seat carrier and stay-in-car base. The car seat carrier clicks securely into the base and compatible strollers, making transporting your little one conveniently easy. If your child will be riding in more than one vehicle, you just need to purchase additional infant car seat bases.
An all-in-one car seat offers a longer duration of use, accommodating the growth of your child and provides all major modes of car seat usage: Rear-Facing with Harness, Forward-Facing with Harness & Booster Mode. An all-in-one car seat stays in the car, it does not click into a separate base or stroller. Because of its bigger size and weight, it is not portable like an infant car seat. If your child will be riding in more than one vehicle, you’ll likely want to purchase an all-in-one car seat for each vehicle.
