How many months old can a baby use a car seat?

[AngeloLynn]

Infants can only use car seats after seven months of age. Below is relevant information about car seats: Types: Infant type, infant-toddler type, child booster seat, and all-in-one type. According to ECER44/03, child car seats are categorized into five groups based on the child's weight: Group 0 (for weight less than 10kg); Group 0+ (weight less than 13kg); Group I (weight 918kg); Group II (weight 1525kg); Group III (weight 22~36kg). Function: These seats effectively enhance child passenger safety. In the event of a car collision or sudden deceleration, they can reduce impact forces on the child and limit body movement, thereby minimizing physical injuries.
