I went to pick up my dd from a playdate with a friend from school. They have a new baby (about7 or 8 months). She is really cute and I started talking to the mom about her daughter. The question of sleep came up and when I asked her if her baby slept thru the night already her response was a surprised "I don't know. I close my door when I go to sleep. (name of nanny) takes care of her." They have a sitter for the daytime, an overnight sitter and a weekend sitter (they have many social events to attend). The kids hardly ever see their parents.
