My nanny seems wonderful, except that she seems to show a strong favoritism for the older, 9 year old child. The 7 year old has more behavior issues, but he is sensitive to this favoritism. I want to bring it to the nanny's attention in a respectful way so she considers it and doesn't feel attacked or criticized. She's a really good nanny, she even has a 4 year degree in early childhood education. My hesitation to say anything is only to not upset a good thing.
