⚠️ Law vs. AAP Recommendations
State law sets the legal minimum. The American Academy of Pediatrics (AAP) recommends keeping children rear-facing as long as possible within the seat's weight and height limits — often beyond the legal minimum age. Always follow the seat manufacturer's guidelines and AAP recommendations for maximum safety.
