Hi, I've got one of these carseats for dd3 who likes kicking her feet. She now keeps kicking the seatbelt out of the "hook" things on either side of the chair, so she's not always got the strap across her legs now, it's only on one side. I was wondering if anyone else has had this problem - is it a design fault, am I not putting the seat in correctly (I'm 99.9% sure I am) or is it because of the moulded seat in our car (Audi A6)? If anyone can help, that would be great!
