When the last of the wrapping paper has been torn and the stockings have been emptied with care, the BBC will bring us one gift more.

A long way from last year’s special, which took place literally thousands of miles away in South Africa, this year’s Call the Midwife Christmas Special tells the story of the Big Freeze of 1962. Luckily for us viewers, no matter how cold the weather, no amount of snow or ice will stop Poplar babies from crowning. So cozy up, and steep yourself a cup of British tea. Here are four reasons why tuning in for the hour-long episode will be the perfect nightcap to your holiday.

It may be frigid outside, but Nonnatus House is always warm.

Warm hearts and warm hearths, there’s no place cozier than Nonnatus, especially on the snowiest of days in Poplar. With Sr. Julienne at the helm of our favorite midwives, the only ice one senses is hanging in the form of icicles from the rooftops—and we’d be glad to be welcomed into the warmth from the cold cobblestone streets. It’s easy to picture the nuns joyfully dancing around a tinsel draped TV celebrating Boxing Day and nibbling on those coveted tea cakes from the pantry. Top off our tea, light the fire—we’re up for the merriment!

Austere conditions make for a modern-day stable.

Lack of power, no water, freezing temperatures, and snow blockages give the midwives and expectant mothers some tricky work conditions in this episode. As we watch the plot unfold on Christmas, the scenes will surely harken back to the nativity story of old and draw many comparisons. “It is very Christmassy and a bit like a modern manger because they don’t have a proper home and it is freezing,” said Linda Bassett, better known as Nurse Crane, in a recent interview about the special.

For sixty minutes, be entrenched in the snow mounds of our childhood.

The moving story at the heart of this snow-filled Christmas special follows the Big Freeze of 1962 which brought the most snow and coldest temperatures East London had seen in three hundred years. This, of course, poses some problems for the midwives as the mountains of snow hardly keep waters from breaking and mothers from delivering. The weather also affects the midwives’ Christmas plans and Trixie’s ski holiday with her new beau is at risk of being cancelled due to the snow. If your hometown is lacking in the snow globe effect this year, then tuning in will surely give you the snowed-in feels.

The Nonnatus women remind us that Christmas lives in our hearts all year long.

Gifts and lavish living are luxuries unknown to the East London tenement dwellers and their nurses. Instead, the midwives find joy in life’s simplicities as they dance in the living room, feast on simple meals around the communal dining table and deliver babies all year long. What more could harken the Christmas spirit than new life to brighten austere times?

The holiday episode will lay the ground for the seventh series of the show, which is expected to return in early 2018.
