I struggle with this too - DD is 8kg and 8 months old and we still have her rear facing, I won't be turning her until I absolutely have to. My guess is that they plan to put the seat in forward facing because then they won't have to turn it later. I wonder if you could somehow get her to do some research, maybe tell her you don't think it's legal and you don't want them to get in trouble and that should prompt her to look into it a bit more. *fingers crossed* I had the same thing with my nephew, his parents turned him when he wasn't 8 kilos and he wasn't 6 months and I worried and worried but at the end of the day you can't parent other people's kids
