The country songstress, 39, shared a sweet Instagram video this week featuring the mother-son duo singing a rendition of classic Christmas tune “Jingle Bells.”  “Bus stop songs with Jace,” she captioned the wholesome clip, which showed the tot energetically belting out the words to the holiday hit. Kramer has been making sure to squeeze in all of the festivities she can this week, as she is preparing for her first Christmas of having to split her kids’ time with ex-husband Mike Caussin, from whom she divorced earlier this year. “We’re getting it all in, making some awesome amazing memories,” the One Tree Hill alum previously wrote on her Instagram story, per People.  Kramer spent the weekend doing some pre-holiday activities with Jace, as well as her 6-year-old daughter Jolie, including going to church, looking at holiday lights and taking photos with Santa and Mrs. Claus. The podcast host also outlined her schedule for the holidays in another Instagram Story, admitting that she is getting used to her new normal of how holidays will look following the divorce. After their week of holiday fun, Kramer’s kiddos will spend a week with their dad, before returning back to her on Christmas Day.  “I’m gonna pick the kids up on Christmas Day. I’m going somewhere because I don’t have the kids for a week,” she explained, according to the outlet. “So I’ll come back from that vacation [on] Christmas Eve. But I’m just gonna pretend like it’s a normal regular day and not Christmas Eve because it’s gonna make me sad.” The actress also shared her plans to expect Santa’s visit on Christmas night, rather than Christmas Eve, so that she can be with her kids when they wake up to all of their gifts under the tree. “I’ll pick them up Christmas Day at noon and then that’s gonna be Christmas Eve,” she stated. “So we’ll put out the cookies for Santa, and we’re gonna leave the letter and the stuff for the reindeers and Santa because its magic—and he’s gonna come Christmas night.” Though a new situation for her, Kramer added an uplifting note regarding all the changes. “We’re making it our own this year and I’m really excited about it,” she said.
