At What Age Can Babies Use Car Safety Seats?

[Rhonda]

Safety seats are generally designed for children over six months old, under eight years old, and weighing less than 36 kilograms. Therefore, infants can start using safety seats at six months of age. The regulations regarding the age until which children should use safety seats vary by country's traffic laws—some specify by age, while others by the child's weight. The following guidelines can help quickly determine which type of safety seat is suitable for a baby: 1. Weight <9kg: Choose a 0-4 years safety seat (strictly speaking, called an infant carrier). 2. 9kg < weight <15kg, age <8 months: Choose a 0-4 years safety seat (infant carrier). For babies older than 8 months who cannot sit up yet, opt for a 0-4 years safety seat (infant carrier); for those who can sit up, choose a 9 months-12 years safety seat. 3. 15kg < weight <25kg: Select a 9 months-12 years safety seat. 4. 25kg < weight <36kg, height <90cm, or 90cm < height <103cm: Choose a 9 months-12 years safety seat; for height >103cm, select a 3 years-12 years safety seat. 5. Weight >36kg: No safety seat is required anymore.
