The Nanny Diaries:

Struggling to graduate from NYU and afford her microscopic studio apartment, Nanny takes a position caring for the only son of the wealthy X family. She rapidly learns the insane amount of juggling involved to ensure that a Park Avenue wife who doesn't work, cook, clean, or raise her own child has a smooth day. When the X's' marriage begins to disintegrate, Nanny ends up involved way beyond the bounds of human decency or good taste. Her tenure with the X family becomes a nearly impossible mission to maintain the mental health of their four-year-old, her own integrity and, most importantly, her sense of humor. Over nine tense months, Mrs. X and Nanny perform the age-old dance of decorum and power as they test the limits of modern-day servitude. Written by two former nannies, The Nanny Diaries deftly punctures the glamour of Manhattan's upper class.
