Here's How Kourtney Kardashian Learned to Accept Sofia Richie

It was just a few months ago when Kourtney Kardashian was left in tears on an episode of Keeping Up with the Kardashians when she discovered her ex Scott Disick introduced their kids to his 20-year-old girlfriend, Sofia Richie. She was pissed she wasn’t told ahead of time. Understandable.

Scott had sought advice from that wise ol’ momager Kris Jenner as to when the first meeting between Sofia and the kids should go down — then later told her when and how it did. “Last night when we got home, the kids were there, so of course they met my girlfriend,” he told Kris on that same episode. “Kourtney goes, ‘You’re a f--king joke... You don’t care. We discussed with the therapist that we were going to wait.’ I said, ‘We discussed with the therapist that we were going to wait until after the new year and after the holiday!’”

Kris also informed him that Kourtney had already introduced her then-boyfriend Younes Bendjima to the duo’s kids, Mason, 9, Penelope, 6, and Reign, 4. “I don’t understand why she can introduce her boyfriend to the kids but you can’t introduce your girlfriend,” she said. “She’s my daughter and I don’t want to go against her, but I see your point, too. So I would just ask, ‘Why isn’t it mutual?’"

But the bickering threesome has come a long way since, even taking family vacations together now, first to Cabo San Lucas, Mexico, then to Aspen, Colorado over the holidays. Scott even posted a pic of the three schmoozing together in Cabo, captioning it: “What more can a guy ask for. THREE’S COMPANY.”

Reports formerly had the two feuding, with Kourtney feeling competitive and thinking Sofia was too young to be in a relationship with Scott and around her kids.

So what changed?

E! News reports that Kourtney realized she had to “keep it cordial” because Scott and Sofia were spending more and more time together, and some of that time would inevitably involve the kids.

"Kourtney has accepted the dynamic of Sofia being Scott's serious girlfriend, but isn't interested in having a close relationship with her. Kourtney is only interested in co-parenting with Scott and their dynamic with the kids," a source said. "Kourtney likes to do activities with the kids with Scott only and doesn't usually love to have Sofia around. She is fine now with Sofia being with the kids when she is with Scott, but doesn't feel they need to all do group things together."

And Sofia’s insecurities about Scott’s relationship with Kourtney are improving since they started spending time together.

"It's tough for her dealing with the fact that Scott has to interact with Kourtney often," a separate source said. "Sofia and Scott's relationship is solid right now and they do spend a lot of time together, but Sofia does get insecure at times and Scott has to reassure her … One thing working to Sofia's benefit is her blossoming relationship with Penelope, Reign, and Mason.”

The trio kicked things off with a dinner at Nobu in Malibu in November, which looked “tense” according to onlookers. The dinner was Kourtney’s idea.

Things aren’t 100 percent perfect, but that’s to be expected, At least they are trying. Kourtney has “a lot of rules and expectations she wants followed,” but Sofia “loves Scott and wants to be with him so she knows this is part of the deal."

AP News just reported that the 20-year-old model — who has been dating Scott for over a year now — is “trying her best to manage the potentially awkward dynamic.”

One insider said: “There has been and will continue to be things with Scott’s family life that bother Sofia, but she is trying to just deal without causing drama. She loves Scott and wants to be with him.”

The source added that Sofia accepts that while she and Kourtney, 39, will never be best friends, she has proved to Kourtney that she is great with her kids.
