I don't have this issue but my thoughts are that if she is going to be driving that kind of distance round-trip, how much do you plan to pay her and does the time you pay her for include her drive time? After all she is going to have to pay for gas, not to mention the increased wear and tear on her car. I know a lot of people choose to commute longer distances for their jobs and accept these things as part of the package of working where they work, but it's still something to think about. You might have to be prepared for her being late if there are circumstances beyond her control (car accident, etc.) and it would probably be a good idea to have someone as a back-up just in case. In the end, all you can do is offer her the job if you decide to have her as a baby sitter and see if she is willing to drive the distance required - it might not be too far for her if she really needs the money but everyone is different. If she ends up being chronically late, then it's time to find another sitter.
