i currently have one DS who goes to an in home sitter the 3 days a week i work. its a great situation, we love our dcp so much. the thread about 2 kids in daycare costs got me thinking. my SIL is getting married in june and like me, she wants alot of children and wants to work part-time. we figured it out that once we have a combined total of 3 kids it would be much more cost effective to share a nanny/babysitter then spread our kids around to the various dcp available in the area. my main question is, how do we split her salary? If i have 2 kids and she has one do i pay 2/3 of her salary and SIL pays 1/3? then what happens when SIL has a 2nd kid-does the nannys pay go up a little and then we split it? i would love to hear any other advice on people who have nanny-shared before! thanks!
