Maybe a bit longer than a few decades ago (that was the 80s and fathers were spending more time with kids), but it is a fact that our society has been changing from one where fathers tended to be more distant and less likely to do things that used to be considered "women's work" (my grandparents and their parents, for example).  Things have changed and in a lot of families there is a work balance where family/home work is shared.  In my house we split all of the work and we help each other out when needed.  Its not rocket science....we're in this together.
