help....

I need someone to watch Rachel and Porter on Friday afternoon from about 2pm until sometime around 3 or 3:30. I have a doctor's appointment and my husband was going to watch the kids, but had something come up at work that prevents him from being able to be home. I called to try and reschedule only the next available appointment they have is for the 3rd week of December! Not happening. So, I know most everyone is picking up kids right at that glorious time, but if anyone isn't and could watch my two for a couple hours, I would be incredibly gratful!!!
