Thinking about buying this carseat as DD is outgrowing her infant carrier and we want to replace our car in the next 6 months so will purchase an ERF seat then. Don't want to buy an expensive ERF seat and find it doesn't fit new car! So this seat seems like a good stop-gap until then. DD is nearly 12mts and is 10.5 kg. How old are/were your LO's when they were too heavy to rear face in this seat?
