How many months old can use a car seat?

[McJosie]

You should wait until the baby is at least six months old before using a car seat. Here is the relevant information: 1. Reason: Babies under six months old have not yet developed their bones to a certain extent, and the support strength of their back muscles is very weak. Using a car seat at this stage could definitely cause harm to the baby, so this point must be noted carefully. 2. Selection of seats: Child seats are generally for children under eight years old or weighing less than 36 kilograms. However, car seats should be chosen based on age groups. For babies under one year old, a rear-facing infant car seat or carrier should be used. For babies aged one to three years, a fully enclosed car seat should be selected.
