“Nothing is sweeter than when the little ones sing Christmas carols 🥺 Although this song isn't just a 'Christmas song' in our house… We sing it year-round here 😜 Bode especially loves it… we've been singing it to him at bedtime for two years 🎶,” Audrey explained in the video's caption.

Last month, the family of five kicked off fall by celebrating baby Radley's birthday. To mark the occasion, Audrey posted a heartfelt tribute to her youngest son, along with an Instagram video featuring moments from her pregnancy and the first year of his life.

“This first year of your life has obviously gone by much faster than the other children's… as any mom of three babies knows. And even though it's been a chaotic year with lots of changes for our family, your sweetness has somehow slowed us down. And I cherish all the baby phases with you because I now know how quickly they go by,” she wrote.

She was aware that the time would come when her baby would no longer need her in the same way: “No baby books, baby apps or doctors can tell you when those days will come. You just don't know.”

“And with your first and even second child, you don't notice them slipping away so much… But with your third, you expect them differently and therefore value them with more urgency,” she concluded. “THAT'S HOW.”
