The switch is based on your child reaching the seat's manufacturer rear-facing height or weight limit, not a specific age. Check the harness height first: if the shoulders sit above the top rear-facing slots, or the head nears the top of the shell, the seat has been outgrown rear-facing. Confirm the correct belt path for forward-facing mode before you reinstall, and follow the seat's stated limits rather than a birthday.
