Call The Midwife fans got an early Christmas present when a clip from this year's festive special was aired on Children In Need.
Viewers were "buzzing" with excitement and "can't wait" for the episode, with nurse Valerie Dyer, played by Jennifer Kirby, returning.
It also features the show's first black nurse Lucille, reflecting the influx of NHS workers from the Caribbean in the swinging 60s.
Watch the Christmas special kindly delivered by @CallTheMidwife1 cast 🍿🎄

The clip begins with Valerie's evening with her fellow midwives being interrupted by an expectant father banging on the door calling for help.
They dash to help a woman who is having a "BBA", or "born before arrival", on the street.
Further details of the plot are a closely guarded secret, but pictures released by the BBC show Sister Mildred, played by Miriam Margolyes.
She arrives unexpectedly at Nonnatus House with four Chinese orphans who are found abandoned in Hong Kong.
The children are being adopted in the UK as part of a global refugee programme.
