Kourtney K. and son Mason Disick enjoy quility time in recent video with baby True Thompson

Kourtney Kardashian shared an adorable Snapchat video of her niece True Thompson playing with her son Mason Disick while the three of them casually spent time together in their Calabasas home.

Kourtney Kardashian, 39, took care of her adorable three-month-old niece True Thompson while Khloe was away, making sure to take a video of the experience and sharing it on Snapchat. At first, fans might think that the video was actually a selfie of the reality TV star playfully sticking her tongue out while using a pink deer filter, but she eventually showed baby True sitting casually on the couch with a white unicorn stuffed animal beside her. She then shifts the video to her own adorable son Mason, 8, who starts talking and making his mom laugh.

The eldest Kardashian sister also posted more photographs of True with different Snapchat filters like prescription glasses and pink ears, captioning it with "I want to suck her cheeks", given that her niece's adorable round face was on full display in the photos. In another photo, it was her daughter Penelope Disick, 6, who happily held True in her arms.

Kourtney seemed to be enjoying her babysitting session with her sister Khloe's child, and Hollywood Life recalled the time Khloe Kardashian, 34, was the one who volunteered to babysit for her sister Kourtney. Given the close family ties of their family, it is good to see them taking care of one another, and making memories with each other.

The night before, Khloe and Kourtney had their own sisters' night, happily making tacos at home while spending some quality time together.

The Kardashians definitely missed Khloe, especially since she has been living away from the Calabasas natives to support her boyfriend Tristan Thompson, who plays for the Cleveland Cavaliers. While pregnant with True, Khloe moved to Cleveland, Ohio, to be near her husband and support him in his NBA career.

Now that the NBA season just finished, Khloe made sure to head back to Los Angeles to spend time with her family, and make up for lost time. The lovely family seems to be enjoying themselves, and as of now, it is unclear if Khloe will be moving back to Cleveland when Tristan suits up for the Cavaliers yet again later this year.
