Instantiate object to move with other gameObject

I am trying to instantiate an object above another moving object, and have that object slowly move down over the moving object it was instantiated over.

What I have done is had the object change a variable on the other object from zero to one.

I have set that object so that when this variable is set to zero, to instantiate the object over itself.

The problem I run into, is that the object doesn't move with the parent

Here is my current code:

 if (variable== 1){
 var newObj = Instantiate(newObj1, transform.position + transform.up * 8, Quaternion.identity);
 newObj.transform.parent = transform;
 variable = 0; }

I don't know why this isn't working. Please help
