Only do weekdays. You will burn out and most people need weekday care. You send her home with dirty diapers, ask her for a wet bag. I would negotiate set hours/days per week so you know how much you will get each week. $11 is great but again, I would contract for a certain # of hours. If she is paying you per hour this normally is more like an employee/employer relationship and she would provide food. If you want to call the shots (days worked, hours, how late your will keep her etc) you might want to look at a daily fee.
