I think it works if you set the rules up front and do NOT interfere with the nanny and her displine. When your Nanny is there, the kids have to respect that she is the boss. If you are a person that can listen to one of the kids have a melt-down or have a few tears or for another adult to take charge without EVER popping in, then it will worke awesome. The cases that it does not work is when 1 of the 3 parties (Nanny, Kids, Parent) is confused about who is in charge and who to listen to. I do feel it is amazing for the children to be home in their own enviroment. I do think preschool is an amazing social thing for preschool years, but the younger muffins would get so much out of being home. You do not really state if you are planning on working with income from home or if this Nanny would just be to aid you while you work with domestics from the home. If it is for income, I think it works well as you have a seperate life but if it is to work beside you, then that is a little odd. When we take our Nanny on vacation with us, the boundaries are the hardest... Good Luck!
