Who has the more responsibility?

I think DE has explained it well.

I'm not sure what you're asking... In the US, the father usually has the most responsibility. If there isn't a father, then the mother does. Once kids leave home, then they're only responsible for themselves until they have a family.

It's hard to say. When I was a child, my dad has more responsiblities to the family. Now I grow up and have my own family. I seem to have more responsibilities as I am in charge of our property. Besides handling the income, I also need to arrange to pay for the charges. I think it depends on which one wants to take the duty or which one is smarter

Usually it's the father, but often now both man and woman in a couple have the same responsibilities.

So far as I am aware we don't really have a "hierarchy."

Our culture, the eldest takes responsibility but for grandchildren it's the grandma takes the greatest responsibility. Just like my wife who never sleeps if her grandkids needs aren't met.

The father is traditionally expected to be the head of the household. These days, though, it appears that this is already hazy because there are families where the wife is the head of the household. As long as the people do it because they love their family, I think it depends on who can do it and not on the hierarchy.

For the most part, if those are my choices, it would be the eldest daughter. Grandmothers are supposed to have lesser responsibility as they age. At least in the traditional American home. Of course, there are always exceptions. My family wouldn’t dare have put the responsibility on my paternal grandmother over my older sister.

I think that it depends on the family. But while the children are small, it is the parents who have the responsibility.

I do not think there is any hard and fast rule left now To each their own Depends on each house and how each one decides. With the system of nuclear family there is no grandmother aroudn to take on any resonsibility.

Usually it is the adult children who have the most responsibility to the family. We spend money to upkeep the family, help with the family repairs, spend time with the elderly parents, and also bring them to the clinic if they are not feeling well.

in my hubby's side, it was the eldest daughter

In my family it was either the mom or oldest daughter in charge of my home.
