Au pair #3 is a dream come true. Sweet, professional, intuitive. She never complains, eats dinner with us (and says 'thank you' after every meal), attends church with us and is a perfect fit with our family. She is always helpful around the house. Finishes her job before I get home. I can't say good enough things about her.
#1 did extend with another family and married her naturalized boy friend (from her same country). They are happy and working on getting her green card.
#2 returned to home country to finish college.
