How Old Should a Baby Be to Use a Car Seat?

[Ellie]

Babies can only sit up completely at around seven months old, so they can use a car seat only after seven months. Below is an introduction to car seats: 1. A car seat refers to a seat secured to a vehicle's seat, serving as a restraining and protective accessory device. Terms such as safety seat, child safety seat, child car seat, and car protective seat all refer to this type of safety seat. 2. Car seats are designed with ergonomic features that match children's body shapes, fully accommodating the physiological characteristics of children at different ages, ensuring exceptional comfort and fit. Additionally, following principles of child psychology, these seats use appropriate materials, patterns, and surrounding shapes to provide children with a sense of security and being enveloped.
