Shifting Gender Roles, Shared Parenting

In this report from the Today Show, the shifting gender roles in American households are discussed. Amy and Marc Vachon discuss their theory of equally shared parenting they split all responsibilities, from making money to childcare, down the middle.

They each work about 30 hours a week and have certain days a week that are marked as mommy or daddy days.

How might this mixing of traditional gender roles affect their childrens understanding of gender roles? Does this represent a genuine change in gender role standards?
