I'm funny about this topic. I'd even suggest going further than the recommended time frame. The main reason is that if you have a collision whiplash and more damage can be done if the seat is forward facing as their bones are still quite soft iykwim? Whereas rearward facing there is less impact on the collision and the position actually protects their neck. They have actually done extensive studies on this in the US and most seats they have recommend rearward facing (although I think there is a semi upright position so they aren't lying completely down) and require children to be rearward facing till 12 months!
