Vector is NOT Adding Elements Properly

[newbiee999]

I have a struct called family which has a father and children (number of children are unknown). Then in add function I add the info of father and save everything in a vector myVec.

struct family{       
        string father;
        string children;
       vector <string> VecChildren; // I am storing children in a vector of string because number of children are unknown
};
vector <family> myVec; // I store whole struct in this vector. 

Then I have the add function and there's a problem here.
Everytime I add children, it adds them properly for the firs time, but when I call the add function the second time, it adds the children from the first time and then adds the children I entered in second time.

Lets say that first time I entered children: 111, 222, 333.
So it adds them.
Then during second time, I enter children: 444, 555, 666.
This time, what it does it that it adds: 111, 222, 333, 444, 555, 666.
So the whole vector has "111, 222, 333" in first element and "111, 222, 333, 444, 555, 666" in the second element.
So How can I make it stop repeating previously added elements.
Below is my code of Function Add()

family myNewFamily;
void Add()
{
cout << " name of father: ";
cin >> myNewFamily.father;

cout << " Enter children: ";
do{
cin << myNewFamily.children;
myNewFamily.children = lowerCase(myNewFamily.children); // a simple function i wrote to convert string into lowercase
myNewFamily.VecChildren.push_back(myNewFamily.children);

}while(myFamily.children != "zzz") // exit loop after user hits zzz

myVec.push_back(myNewFamily); // adding whole struct into myVec
} 

SAMPLE OUTPUT

*** ADD MODE *** 

 Enter the name of the father: dad1
 Enter it's children: 
111
222
333

 myVec[i].VecChildren[j] has:
 int i = 0
111, 222, 333, , 

 *** ADD MODE *** 

 Enter the name of the father: dad2
 Enter it's children: 
444
555
666

 myVec[i].VecChildren[j] has: 
 int i = 0
111, 222, 333, , 
 int i = 1
111, 222, 333, , 444, 555, 666, ,

The problem is that you are reusing the same family object each time you call add. You can fix this by moving the declaration of myNewFamily (line 1) to inside the Add function (between line 3-4).

@ Peter87
Thanks a lot! I was stuck on this thing since last 2 days. And you solved it in a second. Thank you so much! :)
