I agree with all of the above.

When I was growing up in a low-income family, my aunt took it upon herself to suggest that my siblings and I live with her until my parents "got on their feet." Not only did we barely know her (a few awkward dinners at the holidays) but she barely knew us.

We were raised atheist and she presumptuously thought that we'd be better off going to church with her every sunday. She never understood that being forced to hold hands and pray before every meal made us extremely uncomfortable.

She also presumed that we'd be happier living 100 miles away from our school, our friends, the only home we'd ever known with her and her husband.

It created a rift between my father and my aunt that lasted for years, and I still harbour some ill feelings for her judgmental, thoughtless behaviour.

The best thing this aunt can do is open up communication with the daughter independently, talk to her, treat her well, above all get to know her, and set a good example without threatening her livelihood and family. She should also talk to her sister about her concerns and see if they're as founded as she implies, or if they are exaggerated in "the family's" eyes.
