What would you expect to be paid...

My first thought was $100.

But if it were me babysitting, I would give back half. It's very generous. if I'm taking a kid overnight, it's because I recognize that I'm in a position to help and I'm not doing it for the money.

My first thought was $150. If you have a good relationship with her, I doubt she would take that much though.
