Call the Midwife’s Molly Vevers Reveals Worst Part of Those Realistic Birth Scenes

Sunday at 8: 00 p. m. ET, TV Insider talked to Molly Vevers about the elements of Call the Midwife that she finds most difficult to film. Vevers, who plays Sister Catherine, described how certain medical sequences push her past her squeamishness and why those moments land differently on set than they do on screen.

Molly Vevers names the technical scenes as the hardest to film

Vevers said the very technical birth and medical scenes are the main challenge for her. “I’m a very squeamish person, ” she admitted, explaining that she must force herself to look away from the on-set effects and focus on performance. That personal discomfort shapes how she approaches every intense maternity sequence.

Call the Midwife is entering its 15th season and airs March 22, 2026

The series has delivered stories across 15 seasons and remains centered on the midwives and Anglican nuns of Nonnatus House caring for the working-class neighborhood of Poplar in London’s East End. Season 15 arrives March 22, 2026, and the timing of the premiere is the immediate reason Vevers was speaking about the production’s birthing scenes now.

How the production handles babies, props and on-set surprises

Vevers outlined the practical steps used to limit time with real infants: the crew films as much as possible without real babies and reserves the actual infants for the final few shots. She described working with dummy babies when necessary, and how those props can create unexpected problems. In one episode featuring a very premature infant, the dummy kept slipping in her hand because it was covered in a viscous prop meant to mimic birth fluids; she ultimately had to secure it to her hand to keep it steady during the take. She emphasized that the slipping prop was the fake baby, not a real child, and relayed the moment with a laugh to underline the awkwardness.

Sister Catherine’s role surprised Vevers when production realities surfaced

Vevers said she did not think about all those practical difficulties when she first took the role. She recalled being excited after landing the part and then realizing how frequently the scripts call for graphic medical moments. “I didn’t think about that stuff either when I got the job. I was just excited, ” she said, later adding, “Oh no. I just remembered, I hate blood. ” That reaction highlights the contrast between the character’s calm competence and the actor’s behind-the-scenes experience.

Call the Midwife, Season 15, will air Sunday, March 22, 2026, at 8: 00 p. m. ET. More details about episodes and guest roles are expected with the season premiere.
