I guess you would have to come up with a day rate....and it depends also, are these friends of yours that your sitting for? I would think of the meals you have to prepare and the time you spend with the children. They are at pretty self sufficent ages but I know my kids are that age and can be quite busy and need alot more time than you would think. I myself would probably charge $200 for the weekend...I think...lol
