Blac Chyna and her fiancé Rob Kardashian took her son on a grand tour of a fire station earlier this week, and the social media snaps are pretty adorable.
"To a real fire station!" responds King Cairo, whose obsession for all things fire trucks and stations is regularly documented on his mother's Snapchat.
Chyna then filmed King Cairo being greeted by and exchanging high fives with a few fireman at the station.
In the series of Snapchats that followed (and which Chyna later shared on Instagram), the adorable toddler makes his way around the fire station, climbing into a fire truck wide-eyed with excitement and awe.
"It's so big, are you nervous?" Chyna asks her son, who bites his lip and nods while sitting in the driver's seat.
"Don't be nervous!" she reassures him.
"This was an amazing moment with King," Chyna captioned the video.
In the following clips, Chyna tries on one of the firemen's suit for her son. "This stuff is no joke!" she says with a laugh.
Kardashian, 29, who filmed much of the adorable videos for Chyna's Snapchat, appears to be getting along well and bonding with her son in recent weeks.
Meanwhile, Chyna and Kardashian have been celebrating ever since he popped the question with a 7-carat diamond ring last week, just 10 weeks after the two went public with their relationship.
Most recently, the happy couple was spotted out and about in New York City on Wednesday, enjoying some afternoon shopping before hitting Aces strip club that night, where Chyna had a scheduled appearance.
