Emma returns to complete her training at Princess Alexandra Hospital in Harlow, Essex, and is put straight to work when asked to assist with a water birth.

Emma meets Sara and Jake, a newlywed couple in labour with their first baby, along with Beth, who is expecting her first child with her partner Chloe.

Emma's training steps up a gear when she's the only maternity care assistant available. A labour turns into an emergency when the baby moves into a difficult position.

Emma does her first shift in the Neonatal Intensive Care Unit, where critically ill babies receive round-the-clock care. She also meets a pregnant mum with pre-eclampsia.

Emma continues her training and assists in an elective caesarian section. She also meets Erinoulla, whose newborn son has a clubfoot.

Emma's resolve is tested during emergency training, and she also witnesses her first twin birth and acts as official photographer alongside her MCA duties.

Emma meets third-time mum Ashley, who has suffered from post-natal depression in the past, and second-time mum Laura, who has had a difficult time expanding her family.
