Next weekend my cousin's daughter is coming to stay with us for a weekend. She's very interested in the university DH & I went to and is coming to tour the campus. I offered to let her stay at our place and we'll bring her around.

This school is currently her top choice so if she gets in she'll be coming here. Knowing my cousin there's a chance he'll ask if his daughter can live with us.
My DH doesn't have a problem with it. But I want no part in it!
For one she'll be in college, away from home. I do not want responsibility for anything she might or might not do. Any trouble she might get into. How would I establish rules and curfews? We have a baby at home!

Two: money. She can't live here for free. So what do I do? Charge family room & board? Do I cook for her? Clean after her?

I talked to my mom and she agreed that's too much to take on. So if my cousin's daughter does end up going to this uni and my cousin does ask we're going to say no thanks. But if she can't get home for break she is more than welcome to come stay during break. And we'll def occasionally invite her for Sunday dinner, etc.

What would you do in this situation? Would you take on the responsibility of someone else's child?

(I would absolutely do it for our nieces and nephews bc I know we have authority. When it comes to anyone else that's tricky)
