Six minute's for review seems awfully tight for a review, but I guess it was more of an "@liamhuber fyi"?

Anyhow, content and location seems fine so I approve. Only thing I would add is that there's no way I'd commit myself to maintaining this many copies of what needs to be the same (doc)string. It's your package so do what you want, but I would try to find a way to centralize some of the shared content to guarantee that it stays synchronized and save time during changes, e.g.

HARED_ARGS = """
    foo (int): foo's.
    bar (float): bar's.
"""

class Parent:
    __doc__ = """
    This is the parent class.
    
    Args:
    """ + SHARED_ARGS + """
    
    Now I'm done talking about it.
    """

class Child(Parent):
    __doc__ = """This is the child class.

    """ + SHARED_ARGS + """
        baz (str): It's an arg the parent doesn't have.
        
    A different class suffix.
    """
