So what can fans expect from the Christmas special?
The show's creator Heidi Thomas recently revealed that fans can expect the beloved BBC drama to revisit a storyline from season four concerning the thalidomide tragedy.
Back in season four, Rhonda Mullucks was prescribed thalidomide by Dr Turner to help with her morning sickness and her daughter was born with birth defects in season six as a result.
In an interview with RadioTimes.com, earlier this summer, Heidi said that the Mullucks family will return to Poplar, with Rhonda set to have another baby. The 60-year-old creator explained that the new pregnancy "puts them under a certain amount of pressure and gives them a lot to worry about".

She added: "We haven't actually been with that family for five years, so we're picking up the pieces for them and it makes for a very special Christmas special."
The writer also dropped a hint that Nurse Lucille will be grappling with some tough times ahead.
"Looking forward to Christmas and beyond Christmas, something rather wonderful happens to Trixie," she began, before adding: "Lucille has to contend with a reasonable amount of sadness, and what else can I say? We have a new nun coming to join the line-up, Sister Veronica."
