The Nanny (1965)

Accused of drowning his little sister in the bath, 10-year old Joey (William Dix) is sent away to an institution for therapy even though he claims the Nanny (Davis) is responsible. When he returns home, suspicion is quickly aroused again as his mother (Wendy Craig) is poisoned and his aunt suddenly dies. But Joey continues to insist the Nanny is responsible, turning life into a deft cat-and-mouse game between the equally shady woman and her young charge.
