Kim Kardashian posts photo of 'besties' Chicago West and True Thompson together in Bali

The Kardashian sisters are all about family bonding, and so during the trio sisters' recent trip to Bali, they made sure that their children were in on the fun as well.

No questions asked, the relationships between Kim, Khloe, and Kourtney Kardashian have been rock solid through the years. Like any other family, they've had their fair share of ups and downs, but at the end of it all, their relationships with one another have become much stronger.

Now that they have their own little ones, they've made sure to pass on the bond between them, too. While Kim and Kourtney's eldest daughters North and Penelope are absolute besties, it seems there is another duo that's trying to live up to their cuteness - Chicago and True.

Having been born just a few months apart, it comes with no surprise that the two are already extremely close as toddlers. While it's mainly because their mothers have been putting them right beside each other since they were both born, we have no doubt that the first cousins will end up being each other's best friends in the future, just like how Kim and Khloe call them now.

As part of their favorite "family bonding time", Kim, Khloe, and Kourtney all headed to Bali for a bit of relaxation, and they brought their kids along. Captioning one of their posts as "Besties in Bali", the photo just proves how close the 9-month-old and 6-month-old are, even at such a tender age.

It's not just Kiki and Koko who posted adorable photos of their children, however, as Kourtney, 39, and her ex-boyfriend Scott Disick, 35, shared some of their kids, too.

Clearly still keeping a tight-knit relationship with the Kardashians, Scott posted a photo of BFFs North and Penelope, captioning it "double the trouble" with three heart emojis.

Kim headed to Bali with the rest of the family to celebrate her 39th birthday, which gave them a lot of peace and quiet as compared to the hustle and bustle of Los Angeles City.
