Can You Use a Convertible Car Seat With an Infant Base?

Can you put a convertible car seat with an infant base?

No, it is not possible to use a convertible car seat with an infant base. Convertible car seats and infant car seats are two distinct types of car seats designed for different stages of a child's growth. Convertible car seats do not have bases.

An infant car seat is specifically designed for newborns and young infants. It installs rear-facing only and typically comes with a detachable base that remains installed in the vehicle. The infant seat clicks into the base, allowing for easy removal and portability. They are easy to travel with as well, and click onto strollers! 

On the other hand, a convertible car seat is designed to accommodate both infants and older children. It can be adjusted to face the rear of the vehicle for infants and then converted to a forward-facing position as the child grows. Convertible car seats do not come with an infant base, as they are intended to be installed directly in the vehicle and cannot be easily detached like infant car seats or be clicked onto strollers. Most families find they need a convertible car seat in each car the child regularly rides in. Some convertible car seats can be used with newborns (with the included infant inserts), however, you will need to unbuckle and take your baby out every time you get out of the car. The car seat stays in the car.
