Sitting Pretty is a 1948 American comedy film directed by Walter Lang from a screenplay by F. Hugh Herbert, adapted from the novel Belvedere by Gwen Davenport.

[3] The film stars Robert Young, Maureen O'Hara, and Clifton Webb, about a family who hires the mysterious Lynn Belvedere to babysit their rowdy children.

In the suburban Hummingbird Hill, lawyer Harry King and his wife Tacey have trouble retaining a nanny for their three young, rambunctious boys: Larry and Tony, both of whom get into frequent mischief with the family dog Henry; and baby Roddy.

When the latest in a string of servants (all women) quits, Tacey advertises for a replacement and hires Lynn Belvedere sight unseen.

Before Harry goes on a business trip, Tacey agrees to take Roddy and sleep over each night at the home of their friends, fellow lawyer Bill Philby and his wife Edna, just to squelch any possibility of scandal in the town over her remaining in the house with Belvedere.

Nosy neighbor Clarence Appleton notices the lights on and investigates, soon spreading scandalous rumors linking Belvedere and Tacey romantically.

In the meantime, we learn that Belvedere has spent the past few weeks secretly researching and writing a salacious account of the goings-on among the residents of Hummingbird Hill.

Hammond fires Harry and Bill, and then announces his decision to sue Belvedere, who is pleased, as he expects the publicity to increase sales of his already popular book.
