Jacques became pregnant in 1952, but worked through most of her pregnancy, appearing in the Players' revue "The Bells of St Martins" between August and November 1952: she slid down the table and did the splits at the end—something "The Times" thought was "especially good", although "The Manchester Guardian" considered that she was "monumental of person but surprisingly thin of voice". Le Mesurier reported that he was "faintly relieved" when the revue came to an end because of her exertions, added to which she appeared in the 27 episodes of the third series of "Educating Archie" between September 1952 and June 1953. She then directed—but did not appear in—the Players' Christmas pantomime of 1952, "Babes in the Wood". In March 1953 Jacques gave birth to her first son, Robin, and returned to work after a few days to film "Up to His Neck". Later that year she provided the lead alongside Le Mesurier in the 38-minute "movie-masque" "The Pleasure Garden"; filmed in 1952, it won the at the 1954 Cannes Film Festival. From October until April 1954 she was in series four of "Educating Archie", while in December 1953 she also appeared in and directed "Cinderella" at the Players'; "The Times" commented that "Miss Jacques as actress, playing a deliciously arch and absent-minded Fairy Queen, goes a long way to retrieve the failure of Miss Jacques as dramatist".
