Love Is at Stake(1957)

Ma Femme, Mon Gosse et Moi (L'amour est en jeu)

Bob, a talented draftsman, and his young wife Marie-Blanche, a young antique dealer, adore their only son Gégé. But for the most trivial of pretexts, the couple often quarrel. A more serious quarrel leads to separation and divorce proceedings. Gégé spends a week with one of them, and a week with the other, each vying with the other for the little one's affection. But Gégé realizes that he can perhaps initiate a reconciliation.
