Sorry to hijack this thread, but I wanted to ask a question about the 12 kilo thing. I went to change our capaule to the rearward facing carseat this morning at the restraint fitters and was having a look at the book that came with that and my rearward facing only seems to last up to nine kilos, not twelve. Is it safe to leave him rear facing for longer, or should I turn it round at nine kilos? He's only 7 kilos at the moment so we have at least two months to go but I'd still rather have him facing rear after that and we really can't afford another car seat.
