Polly, played by Julie Hagerty is Jamie's slightly insane babysitter. She usually gets people involved in her own problems, such as the time when Malcolm had to keep a secret about Polly stealing back her ashes. She also dated Abe and Craig at the same time but in the end admitting they are more of a distraction to her career. She refers many times to family issues such as court cases. Polly disappears by the end of season 5, and by season 7, it is revealed that they have a new babysitter for Jamie.
