Does the baby car seat need to be selected according to the baby's age?

Baby car seats do need to be selected based on the age of the baby. Infants of different age groups have differences in physical development, weight, and height, so it is necessary to use different types and sizes of safety seats to ensure passenger safety.
Specifically, for a period of time after birth (usually 15 days to 1 year old), infants need to use a rear facing car seat due to incomplete bone and muscle development. This type of seat can provide better head and neck support, reducing the risk of injury in collisions.
As babies grow up (from 1 to 4 years old), their weight and height gradually increase, and forward facing car seats can be used at this time. This type of seat design is more in line with the body shape characteristics of larger infants, providing better body restraint and protection.
When infants reach the age of 4 or above, their height and weight have approached or exceeded the applicable range of certain child safety seats. At this time, height increasing seats or seat belt fixed height increasing pads can be used. These devices can help babies better adapt to the height and shape of car seats, improving comfort and safety while riding.
