SIL has just started to put her 5 month old DC into a forward facing car seat. She has a 3 door car and says its too difficult to keep him rear facing, and as he's 9kg now the instructions on the seat says its safe.
I'm no expert, and I don't know the ins and outs of the law on this, but I have been led to believe they need to be at least 9 months to be forward facing. Am I completely wrong on this one, or should I try to persuade her otherwise? She wouldn't do anything dangerous on purpose but I can't help but feel she's being willfully ignorant so she doesn't have to struggle with the seat anymore.
