While guiding them, North – who had Kim style her hair in her signature ponytail earlier – holds the cups of her younger sister Chicago, five, and younger brother Psalm, three, as they pour almond milk and add the ingredients.

She also helps them scoop ice cream and encourages them to customize their own drinks complete with generous amounts of whip cream, chocolate syrup, caramel syrup, sprinkles, and strawberries.

Big sister duties: Kim Kardashian’s eldest daughter North, nine, proved to be the best big sister as she helped her younger siblings Chicago, five, and Psalm, three, make chocolate milkshakes on Monday evening

In the clip, the three siblings rocked chic T-shirts as Chicago and Psalm enlisted the help of their sister North to make two milkshakes.

‘We’re making chocolate milkshakes!’ Chicago and Psalm exclaimed enthusiastically in unison at the beginning of the video.

At one point, North scooped ice cream out of a carton with ease to her own surprise.

In response, Psalm compared her strength to that of the Marvel superhero, Hulk.

Throughout the rest of the clip, they continued to joke about the the incredible hero’s signature move and gave their best performances of the ‘Hulk smash’ while making their milkshakes.

The kids adorably helped each other out in opening containers, adding ingredients, and even sprayed whipped cream in each others’ mouths.

At the end of the clip, Chicago and Psalm once again joined together in unison and said, ‘Bye! See you later!’ before North picked up the camera to record her siblings enjoying their milkshakes.

North, Chicago, and Psalm are three of four children shared by the recently divorced, former couple.
