DC Girl, I guess I am lucky ( thoug I do nto believe in luck) that I am still happy in my marriage. I have a son ( 2 year old) but I do not expect him to look after me when I am old. Having children just bring joy for the both side of the family and especially for the new parents. I do beleive in having kids ( but no so many of course) after all we have to continue the world with new generation. Well, good luck to you all !!!!
