The birthing scenes were real. Catherine Frot took training to become a midwife and actually delivered five babies on camera. Because of this, while the action is set in the Paris region, the birthing scenes were filmed in Belgium as French law prohibits the filming of babies younger than 3 months old.
Claire tells Beatrice she is 49; Beatrice replies that she always looked older than she actually was. In reality, Catherine Frot, who plays Claire, turned 60 during filming.
