How much should I charge?

kelle017

I'm watching one of the families overnight next week.  Thursday afternoon-Friday early afternoon. 4 kids (2 3 1/2 year old's and first and second graders).  I'll have to get the oldest 2 from school, do homework, make lunches for the next day, baths,bedtime etc... and then get them to school the next morning. I'd also have to take care of the dog (it's like 3 months, I think)

I haven't done an overnight in a long time, and I don't remember what I made from that.

What is fair?
