Yes this here too! I have an older son, younger daughter. We've had a dollshouse, pram, play kitchen etc as well as cars, balls, ride ons since before my daughter was born. The dolls house and kitchen basically sat gathering dust, as did most of the dressing up. The pram was used occasionally as a walker, but if left to his own devices DS didn't go for stuffed toys, dolls, arty things or role play. He was all about building, destroying, cars, balls, things which moved.
DD however the first time she propelled herself across the floor it was to get to the dollshouse. She enjoys playing with balls, ride ons etc but seems to gravitate more naturally towards stickers, art stuff and role play with her doll or other toys.
I can't say I haven't subconsciously added to the bias in anyway, but they both have access to all the toys and seem to have natural affinities to particular ones.
