Would appreciate any advice if anyone knows the answer.....Our dd is just over 10 months old, is 19lbs, and fits the car seat very well, not up to the top of the seat at all yet. She is slim, and fits widthways too. I want to keep her rearfacing for as long as possible, will be getting a rear facing next, I checked the weight limit for the Cabriofix, and it is 13 kgs or 28lbs, she has put on that in 4 months previously - so could potentially be under the weight limit still at 13/14 months - question is, if she still is fitting into it comfortably, do I go by the weight, and move her as soon as she hits that? If this is over a year, do I then have to move her into the next size anyway, even if she has not reached the weight or height limit?
