It's true the families will always do what is best for them, so we have to learn to think as business women and the income we need to earn and do what is best for us. We can't always think with our hearts. But you do want to be up front and professional and make sure you are making a solid decision. Give the old family lots of notice if you let them go to be fair. I admit that I am like Reggio and stick with families to the end, which is usually JK, because I believe in loyalty, but sometimes you have to make difficult decisions.
