How Many Months Old Can a Child Use a Car Seat?

From birth to 12 years old. Related information: 1. Classification: Child safety seats are divided into four categories based on the child's age and weight: Group 0+: Infant type (birth to 13 kg, birth to 18 months). Group I: Infant and toddler type (0-18 kg, newborn to 4 years old). Group II: Toddler and child type (9-36 kg, approximately 9 months to 12 years old). Group III: Child type (15-36 kg, approximately 4 to 12 years old). 2. Note: For children under 9 kg, it is essential to purchase a rear-facing seat to protect the baby's head and neck and avoid the strong impact force during braking.
The usage time of a car seat mainly depends on the baby's physical development. My second child could sit steadily in an infant carrier car seat at just over four months, but the doctor said newborns should use a car seat right after leaving the hospital. Remember one strict rule: the baby must weigh at least 2.3 kg to use an infant carrier, which is why many premature babies need to stay in the hospital longer. In China, children under 1.5 meters tall are required to use a car seat, but in practice, you should choose by stage: infant carriers are generally used up to 13 kg (around 1 year old), convertible seats can be used until 4 years old, and finally, a booster seat until about 12 years old. Last week, my best friend took her 3-month-old baby on a road trip in a car seat, and the baby cried terribly because the neck support was too big—choosing a seat really depends on body size, not just age.
Just experienced the confusion about children sitting in car seats. The community nurse said that a baby carrier must be used from birth, but the elderly claimed that the baby can only sit in it after three months when the bones are stronger. After checking the information, I found that the American Academy of Pediatrics has clear recommendations: newborns should use an infant carrier when leaving the hospital, and it must be rear-facing until the baby weighs 9 kg. My child switched to a rotating seat at five months, and at that time, the weight was just 7 kg. It is recommended to record the baby's weight and height monthly. Many brand seats claim to be suitable for ages 0-4, but in reality, you need to check that the position of the three-point safety belt buckle is not higher than the shoulders. Also, note that thick clothing in summer may take up space in the seat.
Here's how I did it: From birth to 9 months, I used a rear-facing infant carrier with the seat angle adjusted to 165 degrees to prevent milk aspiration. After turning one year old, I switched to a forward-facing seat, but the pediatrician said the ideal scenario is rear-facing installation until at least 2 years old. Last week when dropping off my niece at school, I noticed she was still using a high-back booster seat at age five. Her mom said it was determined by height—if the seatbelt rests on the belly area, it's time to switch to a backless booster. The age guidelines in the manual are just references; the key is whether the child's knees can bend naturally when seated.
