Episode 5

There's tension at Birmingham Women’s Hospital fetal medicine centre, as 19-year-old Billie-Joe has surgery to save her baby daughter while she is still in the womb. Billie-Joe's twin pregnancy has developed TRAP sequence, which means one of the twins hasn’t developed properly and has no heartbeat.

We also meet first-time mum Mini, who is less then five feet tall, and her partner Connor, a six-foot powerlifter. Once medics have located scrubs large enough to fit Connor, he joins Mini in theatre and is overcome with emotion when he meets his son for the first time.

Kui and her husband Shun already have a ten-year-old son, Marco. After almost a decade of trying, Kui is now pregnant with their second child, but she has been diagnosed with a potentially life-threatening condition called placenta accreta. After her baby is delivered by caesarean section, the surgeons must wait to see if the placenta detaches within a critical two-minute window. If it doesn't, they may have to perform a full hysterectomy.
