Return to Question

I have a function which return instances of the class Parent:

def generateParent():
 do_stuff
 return Parent(some_parameters)

Now I want to init a subclass of Parent with the results of a call to generateParent():

class Child(Parent):
 def __new__():
 return generateParent(some_other_parameters) 

The problem is, when I override some methods from Parent in Child and then call them in instances of Child in my program, the original Parent method gets called instead of the new one from Child. Am I doing something wrong here? Am I using the correct design here for my task?

EDIT: I don't have access neither to Parent nor generateParent() ###Solution(thanks to @Paul McGuire's answer):

class Child(object):
 def __init__(self):
 self.obj = generateParent()
 def __getattr__(self, attr):
 return getattr(self.obj, attr)
