I support teaching all kids what it takes to exist, regardless of gender.
I just popped in to say that back in the long ago, in my family, only so much help cleaning up was tolerated from men-folk before they were exiled to football on TV so the women could sit at the kitchen table and talk. Trying to assist in cooking was nearly impossible by anyone who wasn't my grandmother or the aunts that had been cleared for assistance.
I was taught to cook and clean by these same people, but it was clear that at big family meals like Thanksgiving that most of us were in the way if we tried to assist.
I guess what I'm saying is, for sure teach everyone all of it, but big meals might not be the best time. (depending on size of family and a variety of other factors).
At least clear your plate to the sink! :)
