We are about to move to a new town and put our 19-month-old son in a new daycare (which is another post I have to write!)--anyway, we're hiring a college girl for 3 hours a day in the evening to pick him up from the daycare (a 5 minute drive from our house, using our car) bring him back to our house and do dinner and get bath going while we get home from work. She is in college elsewhere--so I haven't met her yet, I've just seen her picture and talked to her on the phone-- but she's a native from this town coming home to live with her parents for the summer, and she gave me three references from other local moms who she's babysat for over the years.

What should I ask these other moms about aside from basic character/reliability questions?
