Infant car seats are rear-facing only car seats that accommodate newborns through their first year of life (give or take!). Infant car seats consist of 2 parts: a base and a carrier. The carrier provides convenience for caregivers, as it allows the freedom to transport baby in their seat when not in use in the car. Infant car seats are often paired with a stroller to create a travel system for ultimate convenience when out and about with baby.
