My 11 month daughter, who was 22 pounds and 30.5 inches at 9 months, rides in the rear-facing position in her Britax Roundabout. What I wonder- Is it dangerous for her feet to be touching the car's seatback, in the event that we are in a crash? I know it is recommended that children ride rear-facing as long as possible. I just wonder if it could hurt her legs if we were in an accident. Should I move her to forward facing as soon as she hits that 12 month mark?
