Certain inclinations will bear out regardless of toys available. I never played much with dolls - I had Dawn dolls, not Barbies, and made them clothes and furniture, but didn't play much with the dolls themselves. It isn't that dolls weren't available, they just didn't interest me!

That said, we always had building toys available, blocks and other building things, and we all played with those a lot, regardless of gender. I am the only one of my siblings that is not an engineer of some sort, but I was always more interested in crayons and things to draw with than toys, anyway!
