The weight at which an infant can transition from a rear-facing infant carrier to a forward-facing car seat varies by the car seat manufacturer and specific car seat model. However, a general guideline recommended by many safety organizations, including the American Academy of Pediatrics (AAP), is that infants should remain in a rear-facing car seat until they reach at least 2 years of age or until they exceed the height and weight limits specified by the car seat manufacturer.
The height and weight limits for rear-facing car seats can vary significantly among different models, so it is essential to refer to the specific car seat's instruction manual for the manufacturer's guidelines. These guidelines will provide information on the maximum weight and height limits for rear-facing use and when it is safe to transition to a forward-facing car seat.
Always prioritize safety when choosing and using car seats for infants and young children, and ensure that the car seat is properly installed and correctly fitted for the child's size and weight. Additionally, follow the recommendations of your local traffic safety laws and consult with a certified child passenger safety technician if you have any questions or concerns about the proper use of car seats.
