Actually C is nuts on motor vehicles and most car journeys are broken up with shouts, of TWUCK, LOWWY, MO' BIKE, CAR, VAN, BUS, NEE NAW....ad nauseum (lowwy and nee naw being about her fave), she got a tenner from my nan for her christening today and ended up buying her a set with a train, plane and helicopter in it as it seemed more her than the fairy princess set and she has several cars, a monster truck and some of our old die cast Minis collection but i could never bring myself to buy the rug for her as i knew id get 'hmph your turning her into a boy'
So if this uns a boy its having a rug whether it wants it or not and i highly suspect C will get a lot of enjoyment from vrooming her various cars along it too lol
