importance of daughter in your life?

I think this really depends on the culture and the dynamic of the family. I think the previously mentioned cultural norm in China is a good example. In America, I think that it's usual for children of both sexes to care for their parents in the same way, but it can also depend on the family dynamic. If the mother is a stronger person in the family, then the daughters may take on more responsibility than the son for caring for the other family members, and it can switch if the father is a stronger figure. In my own family we all care for each other unconditionally, but I tend to take the first steps in caring for my parents because I live closer to them and I talk to my mom every day. My brother doesn't have that luxury, so it changes our situation a bit.

In China,I think the son care the parents more,because most of the sons still live with their parents after got married,and the daughters just go back to visite their parents during the weekend and holiday,so generally,the time the son uses to get along with the parents is longer than the daughter,but it is not absolute.

It is my experiance that both care equally. However when things go wrong it is usually the daughter that steps in. Of course that varys with every family but in my case it is true. I lost my wife last week and I do not know what I would have done without both her daughters and mine. Son's care just as much but I think not equiped to console and care as are daughters.
